It's a really clever idea to have the towers interact strategically with each other. I think it would've been better if the towers were introduced one by one across multiple levels, although I get it's hard to do that in a week. I say that because I had to keep rereading the description to see what they all did, which sucked some of the fun out of a potentially pretty fun idea. But it's a great concept and it works well. Graphics are nice too. The work shows.
