genuinely dont remember where i found this

its part of the anime girl flying around and shooting shit to death genre, kind of like eXceed or much more notoriously, Touhou, which this game takes a lot of inspiration from when it comes to presentation, from the menus and the soundtrack, to more insignificant details like your characters' (or the boss's) portrait cutting in when a bomb is used, or the way the song title fades into the bottom of the screen at the start of a stage

it seems to feature branching paths for the main campaign, which is nice, but unfortunately i cant read moon runes and I was too lazy to find an english patch when I still cared about playing this so i guess i wont be making any sense of the plot

the gameplay itself is pretty unremarkable for a shmup, probably the easiest ive played, though its very akin to Imperishable Night in that you pick a duo of two characters at the beginning of the game, each with a different shot-type, which i guess adds a hint of depth to this otherwise simplistic game

might replay at some point

Patchouli is the best Touhou Project character dont @ me

Pretty enjoyable game overall, and you might be more open to playing it if you're a fan of the EOSD cast. As others have mentioned its kind of a spoof on Vampire Survivors, though I prefer this game.
The spritework is pretty clean (Patchouli and Koakuma's chibi sprites are adorable), and there's a lot of fun to be had with the progression system as it allows you to slowly build up your stream up of bullets with simplistic patterns and buffs to spec into whatever playstyle fits you most.
It isn't a very difficult game, the basic fairies are easy to avoid and their projectiles are not too impressive, though every once in a while a miniboss will spawn in with more difficult (though not as in-depth as real Touhou spellcards) bullet patterns, which is where most of the challenge comes in.

I recommend it if you're looking for a casual roguelike/shmup that doesn't ask for much time investment from the player.
