The upgrade system in this game is very unintuitive, so it took me some figuring out. Eventually I got it, but I wasted the special "Ken's Rage TM" mode early because I didn't understand how it worked.
The sounds is very low- I played this game on a Raspberry Pi and the output HDMI sound signal is very weak.
