It might just be me, but I must admit that I very much preferred the older flight model. It may be more arcadey, and it may be the AC fan in me speaking, but it just felt right! I would suggest that you use that one instead, because I find it more enjoyable.
My nitpicks aside, I absolutely love your work so far! The game is tons of fun even in this state, and it is clear that you've been putting a lot of love into it. Keep up the good work, buddy!
