There's almost no game here. By wave 6 or some low wave like that you can build almost without thinking, almost never running out of money and filling the whole map with towers if you want. I'm at wave 60 now as I type this, only stopping building to type the review. I'm sitting on hundreds of thousands of money just from typing this out, and I haven't seen an enemy round a corner in a long time. No bugs, perfunctory graphics, no sound or music, almost no gameplay.
