Astronomy, turned into systems you can play

Two titles built in LÖVE and released on itch.io — a cosmic deckbuilder about becoming a star, and a five-minute puzzle about switching a station off in the right order.

PROTOSTAR

Collapse matter into a star
Released · v1.0-rc1Windows · LÖVE 11.5

A cosmic card roguelike deckbuilder where every run forges a star — and you keep your stars. Fuse matter and density into Formations, Collapse them for Flux × Multiplier, and spend Ember on Principles — your scoring engine.

Clear a run to Stellarize into a real star, classified on an HR diagram by how you played, then left behind in a persistent galaxy you can name. Push into red-giant territory for neutron stars and black holes; fuse two objects into a supermassive core.

The shop steers toward the build you commit to, so a chosen path is one you can actually assemble. Win or lose, every run leaves its mark.

UNTIL ZERO

Shut down the station. The core goes last.
GMTK Game Jam 2026Play in browser · HTML5

A quiet five-minute puzzle about turning off the lights. Click a power cell to take one charge; at zero it blows and drains its neighbours — chains cascade with falling tones.

Nine decks, each one shutting down a real system: lighting, gravity, life support… and, eventually, the interface itself. The reactor core must be the last light to die.

All visuals are hand-authored vector code. Audio is CC0. One deck has no restart — you'll know which.
