Fortunately, the final episode ends before the celebrities actually show up; we would've needed standing ovations from the studio audience for sure.
Your point about the combat system makes sense. The gameplay wasn't really the priority with this one, but it could be more varied. If I was to develop this into a full-length game, including power-ups and more "arena"-like settings with more complex enemies would be a good way I go, I think. It's something worth investigating.
I'll look into having more than one song per day at least, and perhaps include a wider variety of pop songs. Right now it's all from a fairly narrow genre, but I'm sure there's some '90s cheese I can dig up.
Thank you for the kind words!
