Holy crap this game needs spell hotkeys. I am literally maxed out and I cannot click the spell button fast enough to kill the invisible bosses for the last couple stages...
You can sell towers after the game ends but before you click the continue button, allowing you to rack in money right before the point bonus for it... hrm....
Ok one last comment, switch jump to space bar and pose to down arrow, and give more boost for tricks similar to Cyclomaniacs and the game would be dramatically better honestly.
Let me clarify that I'm not saying this game "sucks" either, its fine, and its different. I'm just saying that Cyclomaniacs is one of my fave games and found its gameplay more enjoyable and I hope a sequel comes out soon.
Very very impressive... As nearly everyone has said already, upgrades, plane choices, more maneuvers could make this pretty much the best thing ever...
Wow at first I was like, this game is pretty cool. And then I was like this game kinda sucks. And then I was like, nah, this game is prolly gonna be awesome. And then I was like, no, its totally crappy. Don't bother.
