About This Game
BUILD CIRCUITS. WRITE CODE. RTFM.
In this game, you can…
- …cram a working gadget into absurdly tight code limits, like 9 or 14 instructions, until every single word matters.
- …build your own devices in the sandbox, including full games people recreate inside it, like in-game Tetris.
- …wire up microcontrollers, memory, logic chips, and LCDs, then write tiny assembly programs where each instruction can run conditionally.
