Great fun, but sometimes the aircrafts aren't replaced fast enough.
Very well, but sometimes a bit to vague.
You must have read the readme to understand the fuel and xp thingy.
It's the only "Indestructo Tank" game for the calculator, as far as I know. It's also nice to have to "buy" your enemies :D.
Compared to previous version: With the Ion/MirageOS compatibility, it's even better than the previous.
Overall: 9/10, a must-download!
Recommendations: faster replacement of enemies, make the fuel and xp bars broader (to emphasize)
