What is ON&OFF?

This free-to-play, single-player roguelike deckbuilder centers on placing magical cards on a grid during turn-based fights. Cards remain after use; switching one from OFF to ON repeats its effect and sends signals along its arrows, toggling nearby cards between states. You gain new cards as you fight through each run.

+you like experimenting with different builds over repeated runs
