I love iiiiit!
It's super cute, the controls are great, and the idea is so excellent I'm dreaming about an antigravity racing game with this kind of mechanics as I write this.
My intuition failed my twice: when I thought the bigger versoin would be faster (in exchange for smaller clearance), and that it would help me catch more of the down-wind (although after reflection that would be dumb as the mass would cube while the exposed surface would only square) ; but you were smart enough to put advices in the menu and it simply enabled me to see the full game. Thanks!
