This is so much fun, I played it three times. The music and rhythm feel really good. I think it could communicate a bit more clearly in general what is happening and what needs to be done, my first round, I had a hard time figuring out when to hit and where the popcorn pieces were really going. The signalling on the perfect zone I think could be a bit clearer but it feels great when you're in a flow!
Not sure it's very theme relevant, I didn't feel much like I was expanding anything, but I definitely had a great time with it.
