Looks amazing, sounds amazing! Maybe down tap or down hold to drop from a platform... I thought I was stuck till I tried all combos to find drop was down+A, just a minor one. The transition going up tunnels is a little jarring as it looks like you can hop from side to side, but you go straight to the upper level - again, only minor. Not played much more, but will download for the GBC to try some more. And checking out the Kickstarter!!
