To keep it interesting, try recording how long you survive and try to get highscores against your friends! Me and Dulait did every single challenge and survived with a highscore of 45 minutes! After three tries...

Well thank you! Have fun trying it out, up to two players! (more if you put a little effort into duplicating the items with item frames!)
