What the developers have to say:

Why Early Access?

“I am currently developing TOOSIN as a solo developer, but my goal is to expand the team size in the future to maintain stable updates. While the core gameplay systems are already implemented, I decided to launch into Early Access to perfectly polish the graphic optimization, system stability, and overall completeness of the game based on player feedback. I plan to communicate with users and build a better gaming environment together.”

Approximately how long will this game be in Early Access?

“I am dedicating myself to development with the goal of an official release within the 4th quarter of 2026. However, the schedule may be partially adjusted to ensure the highest quality, depending on the extent to which community feedback is reflected during the Early Access period and the progress of development.”

How is the full version planned to differ from the Early Access version?

“In the official version, I plan to add more diverse battlefields, new classes, and corresponding unique new characters. In addition, I aim to provide much more expanded content and deeper gameplay than the Early Access version, including a story mode where you can deeply experience the game's world.”

What is the current state of the Early Access version?

“The core gameplay is stably implemented in the current Early Access build, and players can immediately experience the following content:

1) Over 100 player traits and skill trees across 5 categories
2) Over 20 types of enemy characters with self-learning AI (DDA system)
3) 20 types of weapon-based attack combos and over 40 animation motions
4) Round-based perks (random cards) and 4 types of real-time random events
5) Permanent growth system including permanent EXP, levels, and trait points
6) Mock Battle and Training Map systems for combat analysis and practice
7) An endless stage-based roguelike system that collects and analyzes player patterns

For a more detailed explanation of all currently implemented features, please refer to the 'About This Game' section below.”

Will the game be priced differently during and after Early Access?

“As new content and features are added and supported languages are expanded, the price will gradually increase upon official release.”

How are you planning on involving the Community in your development process?

“I plan to communicate closely with players through the Steam Community Hub and my official Discord channel. I will closely review all bug reports and feature improvement suggestions provided by players and actively reflect them in the development process, creating a game that develops further based on the voice of the community.”

About This Game

Surpass the AI that Learns from You - TOOSIN

TOOSIN is a roguelike action game where you fight against an AI that doesn't just repeat simple patterns, but actively learns your combat style and habits to adapt in the next run.

To survive in the arena, players must overwhelm constantly changing and evolving enemies, pushing past their own limits.

A Self-Learning AI that Adapts to Your Habits in the Next Run

Every detail of your combat habits—such as your preferred attack combos, guard timing, and dodge directions—is analyzed and digitized. Using this accumulated data, the enemy AI will enter the next run equipped with dynamic counterstrategies and workarounds tailored to your playstyle, keeping you under clever, constant pressure.

Total Enemy Adaptability Driven by the DDA System

Depending on the real-time Dynamic Difficulty Adjustment (DDA) value, all enemy behavior mechanisms, including level scaling and attack patterns, change completely. Over 20 types of enemies, each with unique patterns, evolve to become even more formidable based on your skill level, threatening your survival on the battlefield.

3 Unique Classes & Diverse Combo Action

Choose from three unique classes, each utilizing entirely different weapons and combat styles. Chain together over 20 types of strategic attack combos specific to each class to experience dynamic action with heavy, satisfying impact.

Endless Build Variety with 100 Traits, 20+ Perks, and Buffs

Combine 100 different character-strengthening traits, over 20 types of perks randomly awarded in each run, and temporary buffs from special events to craft your own unique builds. Experiment with endless combinations, maximize efficiency, and design your very own optimized combat style for a fresh experience every time.

Fate-Altering Real-Time Random Events

Dynamic, unexpected events add a layer of deep tactical decision-making, allowing you to instantly turn the tide of battle.

  • Ambush System: Fend off sudden sneak attacks and claim massive rewards.

  • Risky Challenges: Take high risks to secure powerful bonuses.

  • Blood Covenant: Sacrifice some of your stats to explosively boost specific attributes.

  • Mysterious Merchant: Spend your hard-earned gold to purchase necessary stats after clearing a stage.

Permanent Progression System

Even when you fall, your efforts are never wasted. Increase your account level with permanent EXP earned through play to permanently boost your HP, Attack, and Stamina. Start each run with more points to test even stronger and more complex builds.

Compete Globally via the Leaderboard

Compete fiercely against players worldwide based on your highest cleared stages, levels, and final scores. Become the ultimate champion and engrave your name at the very top of the global leaderboard.

AI Generated Content Disclosure

Generative AI was used to assist in creating certain in-game UI assets (such as combo icons), the main capsule (cover art), and for code debugging during the development process.
