My thoughts on this game are a blend of mixed and positive. I'll just say out of the box that I am probably not the right audience for this game, apparently it's a fan game for something I don't know anything about.
With that said, I enjoyed this quite a lot! It doesn't really to too much different from Everhood, but that's clearly the point, it's a sort of reskin with a totally different aesthetic, which seems to be the thing this game is trying to do. The aesthetic of this game is the best part of this game, the mixed fonts and scrappy yet clean nature of the interface and artwork is super appealing and I liked seeing all of the new things this game was showing.
The gameplay is good. However, there's a problem that I think even Everhood faces, which is that I don't feel like I'm going with the beat at times. This is a rhythm game, yet I don't feel like what I'm doing is alongside a beat. There's an obvious explanation for this, which is the design of it, it's guitar hero but you're trying to avoid the notes that fly at you. The game is built around avoiding things and while this can work, it means that people will play efficiently rather than playing alongside the beat, because avoiding things requires options (which this game has at times) and those options ask which would be the most efficient way to execute. Either way, I still had fun avoiding things, even if I didn't enjoy the fact that the rhythm element wasn't present.
The music was good, I know that the music was made by someone else (that I think is a part of the fandom this game is in). I'm not a huge fan of rap, but those parts where the melody kicks in are enough for me to enjoy it. There's not much else to talk about it though.
Sorry for the long winded review on this lol, thanks for your time.
