It's a pretty raw game.
The visual style jumps a lot. The difference between the cursor and the characters themselves is huge.
I was constantly catching a bug on the door. When one character reached the door, he was duplicated for some reason.
I would like to be able to restart levels.
The character accidentally flew off the map and this was fixed only by restarting.
The cursor goes behind the objects.
I can only praise the game for the initial screensaver, responsive controls, and level game design. They smoothly and gradually become more complicated, like in some classic flash game "Fire and Water".
