The goal of this game is to step on checkpoint tiles in the level and return to your respawn point.

Press R for respawn.

When you step on any tiles (except the respawn point) and move on to another tile, the previously stepped tile will dissolve.

When you step on the checkpoint tile (black tile) and make the tile dissolve, the checkpoint's remaining number on the top left will decrease.

Once you dissolve all of the checkpoints in the level, the stripe color of the respawn will change to green. Stepping it grants you access to the next level.

From level 2, you can place a tile by clicking the cell; however, each level has a limited number of tiles you can place, so be careful.
