This game was basically unplayable in almost every manner.
When the game did work it was extremely clunky. There were no clear directions so you kind of just have to start clicking away when the round starts to figure everything out. I wasn't sure if I need to click and drag a tower or what, but I did figure out halfway through that you have to click a tower then click the box in which you wanted to place it. Not a huge deal, but a nice tutorial at the beginning could prevent any confusion.
After that the next problem I had was with the towers themselves. I had no clue that the random half of a second message that popped up was trying to tell me something important when I clicked on a tower that hadn't been unlocked yet. After staring at it long enough I could figure out what it said. I suggest a couple of things here. Put a literal picture of a lock over the towers that aren't available or even don't add them to the selection until they've been purchased.
I thought maybe this was happening in the game because some of the towers were blacked out during game play, but they would randomly light up and go dark again for random amounts of time so it really made no sense.
Randomly the screen would change colors. That's not a huge deal, just weird... was that suppose to happen? I thought maybe it was suppose to make it appear like time was passing or something like that.
On to the big problem. The screen randomly zooms in and out and then just gets stuck there. I managed to play one level because luckily it zoomed in randomly to the entry and I could build my towers there, but the level after that it zoomed in so close that I couldn't even place a tower anywhere making it impossible to play, hence my review now.
