I had a fun time shooting the drones! My final wave was 8 with 215 drones killed. A mouse sensitivity option would be great, since even at highest DPI of my mouse, it feels quite slow. There's also lag whenever I am shooting bullets. It's still a perfectly playable framerate on my computer, but not quite ideal. It may be because I still use a slow hard disk for storage or some issue with Wine running this game on Linux. If they aren't already, do make sure the bullets are being instantiated with preload() instead of load(). Moving the cannon feels great and it's really fun watching the drones blow up! Great use of the theme, too!
