Plan your route before you move. Think like, if this goes here then that thing will die or if I dig or burn here I will die. Take your time you have 3 mins.

There are 20 levels but you only have to complete 5 of them at a time to get a password. A couple of levels you may have to think very quickly and if you don't press something quick enough you will die. You may have to try these levels a few times so that you know what is happening and know what to press very quickly.
