Great concept and solid execution here. The animations and art style are fantastic, and the mechanic is simple to understand yet hard to master. I love that you added gamepad support here, too, as it makes such a difference for so many games including yours. That said, I didn't realize that I could use the Start button to immediately start the next round from the upgrade screen until after I maxed out everything—it would have been great to see a hint for that on-screen. I'd been using my d-pad to shuffle the focus back over to play every time which really slowed down the pacing for me.
