Incremental Cubes

Incremental Cubes is a cube-based idle game where players collect and grow cubes to defeat enemies and progress through a deep, incremental system. Developed by Tennpa Games and published by Idle System, Inc., the game features a 3rd-person perspective with a fixed flip-screen visual style, blending simple mechanics with strategic depth, including prestige systems, challenges, and helpers to enhance gameplay.

Incremental Cubes: A Deep Dive into the Addictive, Flawed, and Fascinating World of Cube-Based Idle Gaming

Introduction: The Allure of the Infinite Cube

Incremental Cubes (2021), developed by Tennpa Games and published by Idle System, Inc., is a deceptively simple yet mechanically dense idle game that tasks players with one core objective: collect cubes, defeat enemies, and ascend through an ever-expanding tier system. At first glance, it appears to be just another entry in the oversaturated “clicker” genre—a genre often dismissed as shallow or exploitative. However, beneath its minimalist surface lies a surprisingly deep progression system, a punishing prestige mechanic, and a community-driven challenge culture that has kept a niche but dedicated player base engaged for years.

This review will dissect Incremental Cubes in exhaustive detail, exploring its development history, narrative (or lack thereof), gameplay systems, artistic direction, reception, and legacy. We will also critically examine its flaws, strengths, and cultural impact within the broader context of idle games. By the end, we will determine whether Incremental Cubes is a hidden gem, a flawed experiment, or a cautionary tale about the addictive nature of incremental design.

Development History & Context: The Rise of the Idle Game

The Studio Behind the Cubes: Tennpa Games & Idle System, Inc.

Incremental Cubes was developed by Tennpa Games, a small indie studio with a focus on incremental and idle games. The publisher, Idle System, Inc., has a portfolio that includes other titles like Incremental Epic Hero (2020) and Incremental Adventures (2019), suggesting a specialized niche in the genre. The game was built using Unity, a common choice for indie developers due to its accessibility and cross-platform capabilities.

The development team appears to be small, likely consisting of just a few developers, which explains both the game’s polished core mechanics and its lack of narrative depth or extensive content updates. The game’s Steam release on November 3, 2021, came at a time when the idle/clicker genre was already well-established, with classics like Cookie Clicker (2013) and Adventure Capitalist (2014) having long since defined the space.

The Gaming Landscape in 2021: Idle Games as a Cultural Phenomenon

By 2021, idle games had evolved beyond simple clickers into complex progression systems with prestige mechanics, automation, and meta-progression. Games like Melvor Idle (2020) and NGU Idle (2018) had proven that the genre could support deep RPG elements, while mobile titles like AFK Arena (2019) demonstrated the monetization potential of idle mechanics.

Incremental Cubes entered this landscape as a free-to-play title with optional in-app purchases, a model that has become standard for the genre. However, unlike many mobile-focused idle games, Incremental Cubes was PC-exclusive at launch, targeting a more hardcore audience willing to engage with long-term progression and challenging endgame content.

Technological Constraints & Design Philosophy

The game’s minimalist 2D visuals and fixed/flip-screen perspective suggest a deliberate choice to prioritize gameplay over graphical fidelity. The Unity engine allowed for rapid prototyping, but the lack of animations, voice acting, or dynamic environments indicates a development philosophy centered on mechanical depth rather than aesthetic polish.

One of the most notable technical limitations is the input bug in Tier 8, where players cannot input numbers beyond a certain threshold, forcing them to use autoclickers or manual repetition to allocate skill points. This oversight highlights the small team’s struggle to anticipate endgame scaling issues, a common problem in incremental games where exponential growth often outpaces UI design.

Narrative & Thematic Deep Dive: The Silence of the Cubes

The Absence of Story: A Deliberate Choice?

Incremental Cubes is completely devoid of traditional narrative elements. There are no characters, no dialogue, no lore, and no overarching plot. The game’s Steam description simply states:

“This is a simple but very deep incremental game! All you need is to collect more cubes and keep going!”

This lack of narrative is not necessarily a flaw—many idle games thrive on pure mechanical engagement—but it does raise questions about player motivation. Without a story, the game relies entirely on progression systems, prestige rewards, and challenge modes to retain players.

Themes: Addiction, Progression, and the Illusion of Growth

While Incremental Cubes lacks explicit storytelling, it implicitly explores themes common to the idle genre:

1. The Addiction of Incremental Progress

   • The game’s core loop (collect cubes → upgrade → defeat enemies → prestige) is designed to trigger dopamine responses through constant, measurable growth.
   • The prestige system, which resets progress in exchange for permanent bonuses, plays into the psychological concept of “sunk cost fallacy”—players feel compelled to keep going because they’ve already invested time.

2. The Illusion of Control in a Deterministic System

   • Despite the randomness of cube drops and enemy spawns, the game is highly deterministic—every action leads to a predictable outcome.
   • The lack of player agency (beyond clicking and upgrading) reinforces the idle genre’s core appeal: automation as a form of relaxation.

3. The Futility and Satisfaction of Endless Grinding

   • The Tier 8 endgame (where players face exponential scaling issues) mirrors real-world concepts of diminishing returns.
   • The community’s frustration with input limitations (e.g., the Tier 8 input bug) highlights how game design can inadvertently create artificial barriers that feel unfair rather than challenging.

The Role of Community in Filling the Narrative Void

Since the game itself provides no lore or context, the player community has stepped in to create meaning. Steam guides like:
– “No More Cubes: A Guide to Defeat” (Aurora Latios)
– “Just Kill: A Guide to Defeat Incremental Cube’s ‘Hardest’ Challenge” (Aurora Latios)
– “Kermit’s Guide to Cubing” (OriTheWanderer)

These guides frame the game’s challenges as epic battles, turning mechanical grind into a shared struggle. The lack of official narrative has, in a way, empowered players to craft their own stories around the game’s systems.

Gameplay Mechanics & Systems: The Cube’s Core Loop

The Fundamental Gameplay Loop

At its core, Incremental Cubes follows a classic idle game structure:

1. Collect Cubes – The primary resource, obtained by clicking or via automated helpers.
2. Upgrade Cube Production – Reduce the interval between cube drops to accelerate collection.
3. Defeat Enemies – Enemies spawn periodically; defeating them grants skill points.
4. Prestige for Permanent Bonuses – Resetting progress unlocks prestige points, which can be spent on a 3D skill tree for exponential power increases.
5. Unlock Helpers & Challenges – Automated assistants reduce manual grinding, while challenge modes offer risk vs. reward scenarios.

Combat & Enemy Mechanics: A Minimalist Approach

Combat is extremely simplistic:
– Enemies appear at fixed intervals.
– Players click to attack, dealing damage based on current cube tier.
– Bosses appear at milestone tiers, requiring strategic prestige timing to defeat.

The lack of tactical depth is intentional—Incremental Cubes is not an action game, but rather a resource management simulator where combat serves as a gateway to progression.

Prestige & the Skill Tree: The Game’s True Depth

The prestige system is where Incremental Cubes distinguishes itself from simpler clickers. Key features include:

• Prestige Points – Earned by resetting progress, used to permanently boost cube production, damage, and helper efficiency.
• 3D Skill Tree – A visually impressive (if functionally basic) node-based upgrade system where players allocate points to unlock new mechanics.
• Tier Scaling – Each prestige increases the cube tier cap, allowing access to stronger enemies, better helpers, and higher challenges.

However, the endgame (Tier 8) suffers from severe scaling issues, where:
– Skill point allocation becomes tedious due to the input bug (players cannot input large numbers efficiently).
– Progression slows to a crawl, forcing players to AFK for hours or use external autoclickers.

Helpers & Automation: The Double-Edged Sword

Helpers are automated assistants that:
– Collect cubes passively.
– Attack enemies automatically.
– Unlock via prestige or challenges.

While they reduce grind, they also trivializes early-game engagement, making the first few hours feel slow before automation kicks in.

Challenge Modes: The Game’s True Test

The challenge system is where Incremental Cubes shines. Examples include:
– “No More Cubes” (NMC) – A brutal mode where players cannot collect cubes manually, forcing pure automation strategy.
– “Just Kill” – Requires defeating a boss in one hit, demanding perfect prestige and skill tree optimization.
– “Tier 1: Normal, Broken, and White Only” – Restricts players to early-game mechanics, testing efficiency over brute force.

These challenges add replayability and encourage community collaboration, as players share strategies in Steam guides.

UI & Quality-of-Life Issues

The game’s UI is functional but flawed:
– No bulk-upgrade options for late-game prestige skills.
– Input limitations in Tier 8 force manual repetition.
– Lack of save cloud integration (despite Steam Cloud being listed as a feature).
– No resolution scaling, making the game unplayable in windowed mode for some users.

These oversights hurt the long-term experience, especially for hardcore players who reach endgame.

World-Building, Art & Sound: Minimalism as a Design Choice

Visual Design: The Aesthetic of Simplicity

Incremental Cubes embraces a retro 2D pixel-art style with:
– Color-coded cubes (each tier has a distinct hue).
– Fixed/flip-screen perspective (no camera movement).
– Basic enemy sprites (bosses are slightly more detailed).

The lack of animation (beyond cube drops and enemy deaths) reinforces the game’s focus on mechanics over spectacle. The 3D skill tree is the only “modern” visual element, standing out as a jarring but interesting contrast to the otherwise flat design.

Sound Design: The Silence of the Grind

The game features:
– No background music (only ambient clicks and collection sounds).
– No voice acting (expected, given the lack of narrative).
– Minimal sound effects (cube collection, enemy defeat, prestige activation).

The absence of audio immersion makes the game feel more like a spreadsheet simulator than a traditional video game. Some players may find this relaxing, while others may see it as underwhelming.

Atmosphere: The Zen of Incrementalism

Despite its lack of polish, Incremental Cubes cultivates a unique atmosphere—one of meditative repetition. The absence of distractions (no story, no cutscenes, no complex controls) allows players to focus solely on progression, making it ideal for background play while working or studying.

However, this minimalism also limits its appeal—players seeking narrative depth or sensory engagement will find it severely lacking.
