    paper Moo Monster

    Moo Monster is a mobile game where players collect monsters, build teams, and progress through battles.

    In this project, I worked as a Game Designer focusing on gameplay systems and balance. My main role was to make sure the game feels fair, fun, and keeps players engaged over time.

    Main work:

    Designed and balanced combat systems (damage, skills, enemy difficulty)
    Created EXP curves and progression system for players
    Designed gacha system including drop rates and reward tiers
    Built balance tables in Excel to test gameplay outcomes
    Designed quest system with rewards and progression flow
    Worked on PvP balance and reward structure
    Reviewed player feedback and adjusted systems to improve experience
    Collaborated with programmers and artists to implement updates

    I focused a lot on numbers and iteration, testing different values and improving the system step by step.

    This project helped me understand how to balance a live game and work with a team to improve gameplay over time.

    paper Atomicon – Chemistry-Based Action RPG open world

    Atomicon is a gameplay prototype where players use elemental powers to fight and solve challenges. The idea is to make learning feel natural through gameplay.

    In this project, I designed and built core gameplay systems using Unity (C#). I focused on making systems simple to understand but interesting to play.

    Main features:

    Combat system with elemental skills (fire, water, etc.)
    Status effects system (wet, burn, freeze, etc.)
    Enemy AI (chase, attack, react to player)
    Player progression and abilities
    Simple UI for skills and gameplay feedback

    I built small prototypes and tested them many times to improve game feel and clarity. I also worked on balancing gameplay and making systems easier for players to understand.

    This project helped me learn how to take an idea, make it playable, and improve it step by step.
