nice but... here are some bugs and ideas to make i
This game is really nice. but... there are bugs and it could be better. 1. the bugs. sometimes the shield doesn't work while I have power left, sometimes I can't hit the tanks, almost every time the tank/plane shoots be4 my bullet arrives (and I shoot immediately at them). this is really not funny. and to make your game better, you could add this:
-more locations (new, bigger bases with space for more towers and other buildings like factories that you can build tanks that shoot on their own)
-more units (that are insanely strong (the armor. weapons don't need to be stonger)
-more weapons (all these weapons are the same speed. you could add RPG (rocket propelled grenades), missiles and maybe lasers which are faster then the regular bullet)
-more defenses (dual towers (twin turret), AI towers (that shoot on their own), chaingun towers (shoots weak bullets very rapidly after eachother (very accurate), however it's not affected by weapon upgrades)
-more upgrades (bullet speed upgrade, rapid fire no.11 (then you can just hold mouse button and shoot however, that doesn't cost 100, but 5000.)
-larger area (make base and tanks smaller, decrease all speeds)
-new buildings at new levels (every 10 levels a new location with other buildings (not really OTHER buildings, just EXTRA buildings like you get AI tower in area 3 - Antartica/russia))
-smoke out of the guns after they've shot (tanks too)
I hope I'll see more of you soon.
