THIS LOOKS TREMENDOUS.
The idea on the choices between levels is very interesting and ties with the theme.
Come on!!! Look at this cute tank swiveling his turret around, you can't help but tinker with it ^^ This looks like the best amiga game never made.
The bullets look very good and are very visually apppealing, quite unique style, I don't remember seeing something like that anywhere else.
After a while I have a feeling the levels repeat themself a little.
Gameplay remark> if it is needed to target with the mouse while dodging, a big and visible target reticle following the mouse (that you can follow from the corner of your eye) will help (as the tank is more pew pause pew than a constant stream of fire)
