shouldn't bounce off the green bits, instead I think should lose fuel=0 fuel game over-distance would be the score, and the planets make you lose fuel too.
I like it, and a nice idea for a game...but its too easy in my opinion...maybe make a second one with additional upgrades (maybe turret power/base repair?) and more levels.
I got a(n) A- on easy! My score was 2236513 with a max combo of 102. I scored 140 perfects, 52 greats, and 2 goods. I got only 3 bads and 0 misses! I was playing on 3 speed and had 3 crazy options on. One was Random Speed.
I got a(n) A- on medium! My score was 1086351 with a max combo of 52. I scored 148 perfects, 56 greats, and 2 goods. I got only 0 bads and 5 misses! I was playing on 5 speed and had 2 crazy options on. Great game, I like it!
