I hate to keep writing complaints, but the poison tower seems to spaz. It will shoot multiple shots at the first guy, but once he passes out of its range it stops shooting.
When you completely upgrade a tower the info still reads the same as it did right b4 your upgraded. And you can't even click on towers that are "unupgradable" to see their stats.
I have run the game for about an hour with one blue tower killing everything as soon as it enters the screen. The blue tower is just too strong when upgraded.
A single blue laser tower upgraded to 35 damage at the beginning is stronger than the fire tower fully upgraded. I have had one sitting there for about 15 minutes and enemies haven't entered the board for a while.
There is no way to tell how much money you have in the beta version.
Also, in the beginning the waves are much too easy. Maybe have "Easy/Normal/Hard" modes for added difficulty.
I do like the constant waves of enemies though.
