My music partner will be glad to hear that! Thanks! The buttons were also really fun to work on, since I'm not very used to pixel art.
I think a lot of the problem with not knowing what to do is a lack of rules/how to play and a lack of a thoughtful UI. The randomness, as I've been told, is a bit of a problem and has to do with how I've presented the game and the balancing. Especially with hindsight, I can see how needless it is for the energy stat because you'll almost always have enough energy.
But yes! Thanks for the feedback!
