You know, I don't really like Vtubers. Neither do I like their concept, however, I gotta admit this game is way better than I ever expected.

This is way too good for its source material and on top of it all, it's absolutely free. A fan game made for fans, or people who couldn't really care less for Vtubers like me, I guess. Even if you don't get the references, it's not deterimental for your overall experience in my opinion.

If you enjoy Bullet Heaven games, give this one a chance despite its source material. Although, it could have unlockable characters through challenges like most games in this genre instead of gacha mechanics. I don't think the gacha is intrusive and the game give you a ton of resources to unlock said characters reliably, but I won't lie, I'd rather have a challenge system to unlock the girls. Anyway, great free game to just chill.
