here a good guide how to win, first column all tanky warrior, second column all bomber, third column all mage, then fourth and five column all shooter but put in 3 monk and 1 ice mage
the only thing i found is you can use the water on the cat, get the tape, lift up the blanket and get the key, use the key on second drawer to get the magnet, combine the tape + rope + magnet and use it on the fans, you need to climb your self up the fans, i am stuck
You've probably figured this out already, but this is just part of the scenario!
