The goal of this flip flop game is to collect the mirror shard in every level. Move and jump with WASD or the Arrow Keys. 

Activate your mirror ability with X or SPACE. This ability takes everything on the left side of the dotted line and duplicates it on the right side of the screen, but flipped, like in a mirror. Yellow tiles get reflected, while blue tiles do not.

After retrieving the shard, you have to go back to the portal to complete the level.
