Was messing around on the fan in the tower. Found a potential exploit that could be used if fans are used later in the game (currently only level 12). If you let the fan boost you and then immediately after being boosted upwards press the jump button, you will fly higher. Not only that, but if you mash the jump button after being boosted you can sometimes continue heading upwards. The skybox in the tower is rather low but I was able to hover in place for about 2-3 seconds. Eventually it made me fall, and stopping mashing the jump button also makes you fall. It's fun, so try it out with a friend activating the fan if you can :D Oh, and tell me if there are fans out in the other planets. I'll try to get to them!
