Decent TD game
Selecting towers in clusters can be difficult as they often overlap and the maps also seem a little cluttered. In many TD games you get the option to demolish pieces of scenery to allow you to put towers there and I would certainly have freed up a few corners here if allowed. There were also a few times when spaces were blocked by invisible barriers, I only noticed this on the second map though, not sure if the problem exists elsewhere.
I also have to comment on the grammar, which was awful. Dont want to be some kind of grammar nazi here but I think it could be detrimental to some people playing the game, for example, someone waiting for a wave of ninjas which would never come to deploy insta death turrets (XD). Often the descriptions just didnt make sense, such as the "basic damage turret who just can give the soldier basic damage". I suppose you can work stuff like this out pretty easilly, but it just looks ridiculous. You also seem a little boastful about the ultimate turrets which, to be honest, werent great. Being a "terminator with superior execution" I expected a little more. I think you probably should increase their damage a little, their price could easily go up too as they are fairly innexpencive at the moment.
Other than this the artwork is nice, although the towers are often too big for their spaces and the enemy variety is very limited. I also got the 'enemies enter the maze and just stand at the enterance bouncing up and down glitch' but you seem to be aware of this and it only happened once. Overall a decent tower defence.
Anyway, stick at it. 6/10, 3/5, good effort.
Sorry for the long review...
