Wander is a top-down dungeon explorer. Each run takes you through three procedurally generated floors. Navigate the glowing corridors using WASD or arrow keys, collect yellow star keys, and use them to unlock magenta door tiles. Reach the pulsing green exit portal before the countdown timer hits zero to advance to the next floor.
Red sentinel enemies patrol corridors on fixed paths. Contact with a sentinel costs one heart. You start with three hearts — lose all three and the run ends. Clearing a floor awards points equal to remaining time × floor number × 10, so fast clears on later floors are where the big scores live.
