Hey! 👋 I'm Gleb Tsereteli, a full-time GameMaker programmer based in Finland. I've been working in GameMaker since 2019, doing contract work on numerous games. Beyond client work, a big focus of mine is building Free and Open Source libraries to help other devs.

You might know me from my library GMRoomLoader, which won Best Tool at the 2025 GameMaker Awards.

Join the GameMaker Kitchen Discord to get help with my libraries and hang out with the FOSS GameMaker community.

GameMaker Libraries

	GMRoomLoader Award-winning library that turns rooms into reusable building blocks by loading their contents into the current room at runtime. Build procedural dungeons, chunked open worlds, endless runners, and more.
	Figgy Centralized and persistent live configuration system for seamless game tuning and balancing. Auto-builds a Debug Overlay interface to live-edit values while the game runs, no UI coding required.
	Lookout Compact set of Debug Overlay views for identifying common but often hard-to-diagnose problems. Track memory leaks, stray instances, and other elusive bugs across your projects.
