This is a pretty great rhythm game, and is doubly impressive for being this content-packed and challenging while still being in early access. I was initially worried that the game only using a single button could grow stale as it went along, but the introduction of countless new beat types and balancing multiple beats made for some ridiculously challenging and rewarding stages, especially later on.

The visual style is nice and simple, with a lot of great visual tricks the game pulls to make it a bit more challenging. The theming and story was unexpectedly enjoyable, with good writing that justifies the rhythm games quite well. The music was a bit hit-or-miss for me, although I mostly enjoyed what was here. At worst, there were a few songs I didn't care for, but nothing I found annoying. At the very least, the stages are all mechanically different and fun, so even those are fun to go through.

There's a lot of stuff to do, and I'm glad there's a lot for those who want to seek a greater challenge. Locking harder remixed versions of stages behind getting a good rank was a smart move, and makes accessing these stages more rewarding. Speaking of challenge, the game's hard. It's not too ridiculous to just complete it, since you can miss quite a lot and still pass. However, going for better ranks and trying to get perfect ranks is insanely difficult. I like that, gives me something to keep coming back for every so often.

All in all, a very solid package that will only get better and better as time goes on. While not all the music landed for me, it's a well made, varied, fun, and engaging rhythm game.
