Weeee! I LOVE this game! Tilt controls arent difficult at all; all depends on speed. Touch controls are more challenging, but perfectly appropriate. I havent bought the extra levels yet, and hope that the last one includes a hover height greater than 4 feet above the ground (as perhaps the hint in the level name seems to suggest). Also a little hesitant after previous reviewers description of bugginess after purchase. Lots of fun so far, though!
