A game of my own
Designer & Engineer
A synthwave roguelite action RPG. Everything in its world is a cube, and you are the one cube that can still become something else: pick a chassis, then evolve it room by room through drafted upgrades. Built on Three.js and WebGPU, with its own engine and editor.
A game of my own
Designer & Engineer
A cozy pixel-art number puzzle roguelite with deckbuilding. Every sheep is a number: huddle them to add, play cards to multiply or raise them to a power, and count each nightmare off exactly. Count too many and the extras run off into the dark.
