Easily the most fun i've ever had with a platformer game, I've been trying to beat any route without using the arrow keys, so far I've finished Route R with only failing on level 13 (Which is before any route choices). Its amazing in this game you can beat it with ignoring one of the major movement options, the extending gives so much freedom of movement by itself. It sure takes a while to gets used to but is so much fun since even though it feels a bit random at times its consistent.
