I really like the simple yet stylistic aesthetic, as well as the sound design. All the varying stages with new mechanics also makes for a lot of fun. This is an extremely polished and doesn't feel like something made in a couple of days.
Only issue I had is it looks like there's no "Next Stage" option? I would just go to the menu and then pick the stage that way, but it would be nice to be able to just binge through them one after the other without those extra UI clicks in between.
