ABOUT

Tihomir Tilev

I'm a game designer, developer, and QA tester based in Bulgaria, and most of what I know about making games, I learned by doing both sides of it.

By day I work in QA at SEGA, where I've shipped four commercial titles across functionality and localization testing, including Sonic Racing: CrossWorlds and Persona 3 Reload for Nintendo Switch 2. Working alongside Japanese, American, and European development teams has given me a ground-level understanding of how games are built, how they break, and what separates a well-documented problem from one that never gets fixed.

Outside of that, I design and build games myself. My first commercial game, Skyward Dream, a first-person narrative parkour game set inside the subconscious mind, was designed, developed, and shipped on Steam as a solo project over nine months. Every level, mechanic, and design decision in it was made and lived with by one person.

Those two paths, building and breaking, inform each other constantly. I bring that dual perspective into everything I work on.
