Small games, each built on one idea and carried as far as it goes — a possession-platformer, a clinging-slime puzzle, an adaptive-music shmup, a territory duel, an island adventure. All in your browser, all on my own engine.

A 2D musou prototype: you steer one character and your allies obey sentences you speak or type, like “Hanne, follow me”. German and English. The browser build matches orders offline by keywords and listens through your browser's own speech recognition. Early prototype, with a gamepad or the keyboard.

A collection of fast local multiplayer minigames — grab a friend, one keyboard, no explanations needed. Published April 2026.

A minimal, fast image viewer. Crisp vector SVG rendering (sharp at any zoom, not rasterized), animated GIF playback, GPU-accelerated zoom/pan, rotate & mirror. Built on wgpu.

An open ecosystem for game music as plain-text .track files: compose in Plainsong, share parts on Trackyard, play anything with Plainaudio — all in your browser, all connected by one format.

Branching stories as state, not as trees. A Petri net decides what can happen next, plain text says how it reads — kept in separate files. With PN Editor, VNgine, and a story checker.

A coding agent that starts other agents and keeps working while you are away.
