i tried lot of times. i see on lvl 10, when you jump in the holes, the hand always drop a box so that box close you in a square where you can't move until another box kills you. the only way i found to pass that level was going to die to that spot, and wait for the hand to drop a bricks box or metal box that they keep in the map after restarting level. and then i can pass. if not it is impossible. another bug, if you restart before you die, yo never go to main menu. i finished with -32 lives for example......
