SpritesOut is a tile flipping game like Lights Out. The game features sprites from several retro games and from famous NES titles such as Megaman and Super Mario Bros.
Clear the board of the tiles.
Every time player flips a tile, the ones surrounding it are flipped as well. This proves difficulty to clear the board while tiles flip while flipping/ clearing others.
