I really wanted to like this more. The towers and enemies are well-designed and the game is extremely colorful. However, if they have no target, the towers will space out and turn in random directions. For the fast towers, this isn't an issue, but for the slow ones, this could mean missing several shots and not defeating all the enemies. There was too much random chance involved in the most frustrating way possible. I couldn't go on.

I love this game! The atmosphere it makes is amazing, the effects and sounds are used to great effect! As for the actual gameplay, its a bit rough. Trying to get past Mission four is near impossible for me, and i had to eventually resort to looking up a gameplay guide. If it wasnt for the difficulty spike, I would say this is the best tower defense game there is! There are no intrusive ads, which would break the amazing atmosphere, so thats a plus too.

Been a while since I've played, but it's a fairly good tower defence game, more colorful than any I remember, and sometimes kinda funny with the dialogue! The main irritating bit I remember is if a mission you're retrying has dialogue, you have to run through it all, every retry. Also, probably intentional, but things are somewhat randomized, so that you can play the same mission, in the same exact way, and have very different results! BONUS - my progress was kept after I switched phones!
