At the beginning (lockpick I & II) you open chests with smartness, like a thief. At the end (lockpick III), you understand that the best wy to open them is just to kick them :-)
Suggestion to beat the game: Stick to the right corner and move minimum steps only if you are sure that a laser is going to hit you. For the last part, to the same making synchronized jumps to avoid the obstacle. At this point you only need roughly 10 jumps
Very nice game... it deserves 4/5 even if it lacks basic stuff: a mute button (! in 2014 still exists professional games without mute button!!), some (more) rules explanation and maybe an undo button. Still very enjoyable.
