Feels like Parappa's Scandinavian zoomer son with a Beatmania influence.
Notably the only rhythm game I've ever played where the track is sequenced to loop if you don't FC which is rly interesting and makes a lot more sense for the bosses but makes actual stages end pretty anticlimactically.

The humor is very "love it or hate it" depending on your tolerance for what feels like a mildly modernized version of the late 00s-early 2010s let's play scene, the charm of it alone never made it cringeworthy though and there are some legit good bits in there.

For a game that looks this newcomer-friendly though, the skill ceiling does extend pretty far, about on par with Parappa 2 when you factor in the unlockable harder difficulty. It's incredibly generous with its health system but making mistakes at all (including any inputs that aren't on a note) obstructs your view and it's probably very easy to panic if you're not used to games like this.

This and the prequel sidestory took a swift 2.5 hours which if it appeals to you enough I'd say it's worth the full $15, 100% would def take at least 10 hours assuming you're more consistent with your fixation on rhythm games than me lol
