Not so great. No sell ability for the towers, once you've placed them, they are stuck.

All towers have multi-hit. Meaning that once you have a setup that 'beats' the first level, you'll be able to progress all the way (I went up to 11 before writing this review)

It took me 2 yellow towers, and 3 greens. Then I got bored. The music is also a constant loop, no sound effects, it's pretty boring.

Well programmed, but I think the game should look more interesting. Sure you can do triangles and other geometric shapes, but try adding more colors and shapes.

One more thing, sometimes the bullets hit the enemies and they still don't die.

This game has some promise. You must make sure to make your own buttons. If you think you aren't good with art and illustration, go to the forums and find someone that is. Working with someone that can provide original art will help your games a lot.

I don't recommend.
