This is a 2D collection visual game. In this game, your goal is to pass through many obstacles with similar shapes. The tip of a triangle, a square, or even a liquid container are barriers.

You only have two controls: jump and set flags as you go through the level to win. If you hit a block, you'll restart the level from the beginning unless you set a flag before dying. Flags serve as a checkpoint from which you may respawn. You have just ten flags to use in a single game, so use them carefully.
