If we could disable shadows it would probably be able to run easily on about any hardware. I run on the second lowest setting on intel HD Graphics 620, and it's butter smooth on scren saver (50-60 fps), and between 30 and 40 fps when playing. Maybe an opaque marble could save a few resources for lower-end devices too.
As for the gameplay and the music : simple and nice.
Potato changes the resolution for rendering everything, with an insanely low 320x180 (I don't know who would actually play like this). It does run smoothly on low-end GPUs but is nowhere near looking like enjoyable.
Adding settings for shadows (which can be very power expensive) and reflections (same goes) would allow for higher quality rendering but better performance on every hardware, including low-end, perhaps drastically.
