Hey, great game!
Lol... the car can jump
good work! very fun!... yeah, I'd add a few more planes or something in the first level, or make it shorter. Even if there are multiple levels and this is the easiest, it's still a bit boring when there aren't any planes around at the moment.
Ideas I had:
-Make one type of plane leave behind one of those big craters when crashing, so that you have to jump that crater.
-Have some tanks standing at the side of the road... not on the road but next to it...
What I like:
-The game makes you look at the sky most of the time, so when there is a crator or rock, you don't see it that easily.
-Everything else ... it really is a great game.
What I dislike
- nothin
