Parts
The parts system was fun and all but I could never get enough parts to make any of the big guns like the rocket launcher, during the big toy mode I only got out the first two starting air cannons. Also there was just one level, the only difference was difficulty.
Plus really this is just one of the thousands of other tower defence games. So I think youshould add some more maps and lessen the costs of the big cannons.
bug
there is a problem with the magnet tower if you could get 10 kills with it the upgrading part was bugged you could click on it as fast as you could till the game reconized that it lvled and by then you could have it upgraded to lvl 10 or so
other than that was great game keep up the good work
person below me 2 times
you have to have each of them earn points cuz its no fun like that they have to earn exp each time so you dont upgrade to fast
Great
Only one thing irked me, you spelled Martians wrong.
yeah
I like the idea that you use parts to build your towers, thats original.
however, only being able to upgrade your towers if you get enough kills leaves any new tower you build unable to improve and leaves you with only being able to upgrade a couple of towers.
