Great game
At first I thought this game was overly complicated, until I actually played it, then I found it to be incredible, then I realised it isn't incredible, but addictive.
I really like some of the unique features this game has to offer, but there are other things that could have been included to make it even better.
Graphics: It wasn't the flashiest thing in the world and anyone who thinks that is a fairly new to this world (or extremely different). You could included the option to change the colour of the tank or you could have made the airborne vehicles seem more realistic. Also, you should have used different shaped bombs to make them seem more distinguishing (another good thing to do (IMHO) is to change the colour of the bouncing bombs after they bounce). I like how it was easy to access the graphics quality though.
Style: Extremely unique, but I'm no expert in this department.
Sound: Seemed to me like it was the same explosion again and again and again, but I can't really complain about this too much (a different sound for each bomb perhaps). I thought some good music would be nice (or the ability to change sound settings (including volume of music, different music tracks, and other stuff)).
Violence: Eh, not all that much really, include a better explosion and a bit of fire and the violence in this game would work wonders (again, I'm no expert here).
Interactivity: The experience mode thing is good and everything, but how about a free play mode (no fuel limits and all the enemies are maxed out instantly).
Humor: I smiled a bit but it was nothing special (this catergory is based upon the assumption that humor was not your primary target).
Overall: A good game, some (like myself) may go far enough to say great, but I think it's uniqueness and style doesn't make up for everything it lacks.
Other things that I would suggest (the word suggest has heavy emphasis here) is that pressing the down button would give you greater acceleration toward the ground (and the up button; the reverse).
I like the option to submit the high score, but it does have at least one flaw; upon checking I found that all the tables were filled by one individual.
I believe that the fuel bar in the bottom of the screen should really be a time bar as you waste fuel in mid air and you use the same amount whether you are accelerating or braking. Also, it would be a little hard to blow up an indestructable tank when it hasn't got any fuel at all.
If anybody feels offended by this comment please note it was not my intention and all above text is my opinion not somebody else's.
Good luck with a sequel or anything else you have in mind.
