The help menu seems to be a little broken, the back button is under the three main buttons that I'm assuming are supposed to disappear. The gameplay is a really fun concept, but I struggled to be able to place a healing tower. When I was able to place a healer tower, I was able to do so without enough gold and drop to -10 cash. The player can hit the enemies with so much force that it seems to launch them so far away the game becomes soft-locked. Otherwise, I really like this concept and I think if bounding boxes were set up just outside the screen to keep the enemies from being knocked too far away this game could be a lot of fun!
