This is a fantastic interpretation and application of the theme. I went in a little unsure as to whether I would enjoy a rhythm game, but oh boy I did.
I think the thing I'm most impressed by is all of the small things that collectively improve the experience. The rhythm notes being timed to the beats correctly for all the different songs. Also how the music was thematically match to the foxes' identity.
The final music was an absolute banger, I now realise it was a cover, but gah it really hit just right. The difficulty seemed pretty well placed, I played on normal and had quite a bit of corn left, still felt like I missed fairly often on the triples.
I would have perhaps liked a toggle for the CRT shader, and for just a single turn on 'QE' keypress as I double turned occasionalyl. But these are small preferences and not critique.
Overall this is really great, a very solid game and interpretation of the theme. Thanks very much!
