I had fun but I only made it to level 3 today, might try again later. The idea is fun but I had a few problems with the collisions. While I could always get the cube unstuck, I mangaged to get myself stuck behind the button in the first level. The water was quite frustrating, because I kept threating the corners as rounded while the collision box is square.
Also my bandits moved with random speed from barely at all to lightning fast. Was that intentional? Impossible to beat if the bandit is a blur, trivial if he doesn' t even manage to do half of a trip till the door is open.
