my suggestion is that you make more upgrades. i think that would halpe but all in all it was a pretty cool game

Got to day 5 and go way to hard.
Not much upgrades to chose from either.

The animation's good but the gameplay isn't original,it gets harder WAY too fast,instead of gradually getting harder.

Other then that good job.

It does get a bit hard too fast and the upgrades for your turrets suck a bit as they dont do much more damage. The red guys seem impossible to kill, it takes more than 3 fully upgraded turrets and 7 max power shots to kill.

Not bad though.

But no way near enough variety. Only three upgrades to your three identical towers. I can see why you haven't done a huge amount more than you did, though, since the later levels start getting very laggy.

Don't know if there's an end to the game, either. If there is, you should tell people so that they keep playing through to it - or it's likely people will just give up.
