Time for a week of new game development!
It's a bit rough around the edges, but not bad for a day of work I'd say. I was hesitant with the spanking animation, but it turned out okay in the end, so now I'll be able to devote more time to it in the end. Luckily the main game play is easy to code for this, so I can spend more time on the art. Next I'll probably work on the note frequency and detection, then the note and sensor graphics.
