First all of thanks for the long reply too lol, hope I didn't come off as mean but seems I at least provided some good feedback, a real shame on the music, I always love music in games so that sucks, if you can get it working correctly in an update please do message me again (I've followed you just in case) as I'd really like to hear it as it sounds very good from the start of the tracks!
So for the circle phase I see what you mean with items but as I said the AI just dart off within a millisecond when the music stops so if you could add a little randomness to when they go to the center (just a random delay and the random number gets lower and lower as the difficulty gets higher) THEN I think I'd feel comfortable going for items a little more
lmao I didn't think about refusing to move in musical chairs though XD, I do think there's an interesting idea there in being able to do that lol,
Again hope I don't come off as mean, I really like the entire concept and the game itself is already fun!
