This game was well made, didn't come across any issues while playing. It was really fun trying to optimize a path and the camera effects where a nice touch that made the overall playability of this game awesome. I wish the difficulty curve was a bit more forgiving, as I felt like if I just barely made it passed one wave, the next was not an incremental step but a crushing increase. I think it would be cool to add some different kinds of towers in the future, this may also help with your difficulty curve. Most importantly I had fun playing! Well done.
