Incredible
The best game of its type I've played since Raiden X. The graphics are very good, at firsty they didn't blow me away, but when everything started happening all at once it looked awesome. Easy to play, but challenging at the same time.
One little improvement might be better enemy AI. For example the tanks always fired in one direction, maybe they could at least try and aim at you.
But this is pretty much perfect all round, I reckon it'll do well. Nice work. 10/10
