One of my favorite aspects of the game jam format is that the time constraint often makes it impossible for devs to adhere to genre conventions, and instead forces them to hone in on a single core element or feature that can really shine. POWER is an extremely focused experience, but not at all lacking in surprise and delight.
The mathy audio wizardry behind this game are and always will be far beyond my understanding, but I still never felt like I was playing "wrong" despite my lack of intentionality in which keys I pressed. It was sort of meditative to embrace my lack of understanding, let go, and just jam out to my monkey-at-a-typewriter composition. I wonder if my haphazard playstyle was your intended experience given the impenetrable interface and the fact that there's no way to generate sound without modifying parameters.
Thanks for doing something completely different, this one's gonna stick in my mind long after the jam is over.
