Game and editor systems
The in-game editor, object interaction, Rumi movement, collection systems, and the UI tying those parts together.
Summary
Armin Grbić
Senior Game Developer
I've always wanted to make video games, and I've been interested in every part of how they're made. Learning across those disciplines has given me a broad range of skills, though programming remains my main focus. On my own projects I also handle design, art, animation, UI, and the work involved in bringing a game to a store.

Current project
MiDiO
MiDiO is a room-building and creature-collecting game. Players create small 3D dioramas, populate them with Rumi, and share their rooms through Steam Workshop. Twitch and Firebase integration let viewers participate in its collection systems without owning the game.
MiDiO is available to buy and play on Steam in Early Access. I develop it solo, covering the game, editor, UI, integrations, art and content, and ongoing production.

Multiplayer
Steam sessions, replicated gameplay, server-side state, and shared player interaction.
Gameplay and structure
Cooperative gameplay, player interaction, progression, and shared game state.
Interface
Menus, lobby, HUD, results, and the flow between each part of a session.
Environment and tools
PS2-style art direction, environments, and reusable construction tools.
