Don't think I have seen a rhythm tower defense game, nice work blending two genre's into a elegant fun game.
As someone who sucks at music/beats I was pleasantly surprised I made it past level 20 (first try I got zero because I had no idea what I was doing...)
I like how the beats start simple, but have to admit once they shift from the original patterns I had to just focus on two - could see have a multi/co-op experience would be a lot of fun.
How draw back is I am watching the beats so much I completely miss what is going on in the streets and it starts feeling a little old need some way of changing things up - maybe make the waves into songs so each one feels different.
Thanks for submitting was a lot of fun.
