Incredibly cool and unique! I liked how each round morphed the gameplay and tied into each other. I was not expecting pachinko, but it was fun to see it.
My only criticism is that each area felt too dark and zoomed out. It was often difficult to see what was going on at first. After a new rounds, it becomes evident. But it would have been nice to have a closer view of the pachinko zone, for example, to better see where the balls are landing.
Either way, it's a fantastic concept.
