i quite liked it and seeing my avatar sat in a biplane made me giggle rather childishly - making me giggle is quite a good way to sell me a game usually although i haven't paid for this one yet. =-)
Some nice ideas in there for power-ups; can get fun when you get the hammer or the pinball and hijack lots of tanks and jeeps.
However, you only have a pea shot; it's too easy; completed all 12 levels in first sitting; some stages are too long; not even a simple HS table.
Now get this: when I changed the difficulty to HARD to try it again, my score from the previous run wasn't reset and was used as the starting score for the new run. It means scores increase forever!
