Very wide variety of towers and enemies---I wish there was more info on which towers do more or less damage to which enemies (some kind of enemy library, or info when you hover over them, or even just info in the description about them would be good).
The gameplay is fairly standard tower defense stuff, but I do have to say the tower's creative upgrades as well as the voicelines really elevate this to be probably one of the better TD games made with flowlab.
Now, there are some bugs (you can just click to buy a bunch of towers and they'll follow your mouse...and attack enemies without ever being placed) but overall this is fun and pretty impressive for being made in 2 weeks.
