Beat it. The game feels a bit much like wandering aimlessly. I know 3^6 is only 729 different rooms and you are only in danger in red ones but wandering between them takes a very long time and has no clear objective besides sticking to blue until the end or if you have run out of rooms-- you may well have to go down before you can go up in any given direction. I'm glad there is an end screen, though, that is nice.
