Finally got around to play this! For now I beat the WebGL version however it felt pretty polished and didn't run into any game breaking bugs. It's very, very similar to the Touhou series, but it's fun and the lore is fairly intriguing.
The art is really cool. The sprite work is well done. The 3D-pixelated background gives it a cool look as well (even if I wish the gray sections where a bit more detailed, although IK it's a hard balance to have so that it doesn't distract from the bullets).
The level also ramps up organically, I don't have any complaints in terms of progression or difficulty.
The music is really dope as well. It borrows some elements from Touhou/ZUN but has its own identity.
The boss could do with some animations, tho.
Overall, really enjoyed it so far! Can't wait to see how it evolves.
