As the other reviews said, it's not particularly great. I don't know why the devs released this game in this state, but you can definitely tell it was rushed.
It's buggy, and the bow animation has an annoying startup delay before you're allowed to shoot an arrow, meaning a lot of back and forth to avoid the enemy's attacks and shoot again. It has aimless level design, which is impressive considering it's just a bunch of corridors filled with enemies, and the game never explains the controls to you, you have to figure them out.
It's funny because the devs knew about the problems, and locked away infinite ammos in a secret room at the beginning of the game, as a bandaid to this game's issues instead of fixing them. If you still want to play the game for yourself (the art is nice after all), at the beginning, go left and kick the wall a few times, then go left to get the infinite arrows.
The art is definitely the best part of the game, and I appreciate the fetishes here, but you need to actually beat the game to see the whole gallery, which is also buggy too, with some scenes not even functioning.
I've seen on their DLSite page this is their first game, so I'm more enclined to be lenient, but I hope they learn from their mistakes here and make a better product in the future, especially since they charge money for this.
