Hello thanks for playing my game !
I'm happy to see that you could finish at least 1 level, you can push the box when it is against a wall in the opposite direction. You can restart the level by pressing escape and then press play, it will restart the level you were currently at.
And to awnser your question, nobody put the bucket on our head, we just slipped onto it, it was there, alone, sad...
And we can't see through the bucket, we just guess which direction to go with cerebral wave
