honestly one of the worst games i've played. no thought into this at all. no matter how much you upgrade, you still get screwed over by obstacles. when you lift off, at high speed it is impossible to dodge a bunch of blimps and you either flip over or blow up
seriously, those gates that speed you up don't help a single bit. they pretty much pollute the airspace the same way as all other aircrafts. you crash into a post and it makes you do a hundred flips and you end up facing downwards
