So let's see, your enemies include ... normal sealife ... pig-fish ... fish in gimp masks ... a wanna-be evil staticy TV that was rejected from Silent Hill ... the illegal nuclear dumping industry ... angry pulled teeth ... and angry pots of grass? I am in awe ....
I didn't even notice there were missiles until I had quit, and then went back to try them. I love that they just circle around waiting if there's nothing to attack (or if they run out of targets).
I notice that there's not much reason to stop firing -- your crab arms don't seem to be checked for hits -- so it would be awesome if there was a "constant autofire and click to fire missiles option" to allow it to be played fully mouse-only.
Hm, when I hear "tank battle" I tend to think of slow vehicles with faster-turning turrets. The graphic used sort of suggests that, too. Aside from that, what's there is a fairly solid core game that needs some polish and a lot embellishment to stand out.
Hm, I don't really understand the thing about turning up flash's data limits reducing lag. This game, as far as I can tell, stores about 3kb in .sol files, which are the only thing that setting affects.
I'd probably play through this again on this site if there were badges here :).
