This game is really cool! It's the closest I've ever gotten to actually being hypnotized. I felt pleasantly relaxed and had a sort of brain fog afterwards.
I will say, for whatever reason having to catch the motes instead of just matching the rhythm broke the visual illusion for me and seemed to lessen the trance state. I would love it if there was a toggle to turn it off, but maybe it's important, I don't know a lot about hypnosis.
