Wow, gorgerous art, the music and sound effects are also incredibly fitting and well done, the kitsune japanese vives were blooming from every part of this game, even the transitions on the menus, it feels and plays like a Touhou game, which I love, I liked it quite a lot, and the characters portraits are amazing, with the little dialogues, I really thought it was like a full game out of Steam. I want to point out some things I found that I would take a look again if you want to update the game later on, these are my nitpicks, I like the game a lot already, and these are just my opinion:
The enemy waves feel nice, but the bullets are very difficult to see, it is possibly because the background is very bright, more contrast on the bullet edges or more color contrast could help. The boss is nice too, but the bullets are extremely fast and small, which are very hard to track, the difficulty spiked drastically from the enemy waves to the boss.
