This slapped my ass and called me Willy. What a goddamn cool game, this is just so much fun and has so much promise.
Rhythm shooters are something that I think has a lot of potential and this is probably something that I've wanted to see, and this nails that core gameplay loop wonderfully. Being able to just put on a song and vibe in a flashing, neon-lit world while blasting off hordes of enemies is potentially a fantastic way to unwind.
If I had to really buckle down and critique something, nothing feels limper than being in the middle of a rockin' part of a song and then your left toe brushes up against a toe and suddenly you're booted out of the experience. I would lean into the fact that the gameplay is a compliment to the music and instead keep track of (and display!) how many times the player would have "died", displaying a final tally at the end. The end result is to enjoy the music with a show, after all, suddenly getting booted out is a bit of a downer.
Outside of that, though, the only thing I really can say is that I want more. More. In fact, I would dare say I want moar. If you imagine me making grabby hands in the general vicinity of this game, that's basically the sum of my feelings. More types of enemies, more ways the environment can change with the song, more background elements flashing in time with the music, send me to synesthesia heaven and fuck me up.
