This reminds me of Yoshi's Cookie which I *loved* to play as a kid. That being said I'm not a puzzle aficionado. While I was able to figure out the basic gameplay, almost everything about the crafting part confused me. The descriptions talk about physical damage and hits and at first I was like "How exactly does it translate to my skills in the pattern table?"
It took me until the third level to realize that like, these attributes aren't applied to *you*; they're applied to the dresses and whatnot of whatever Touhou girl is asking you to make their clothes.
While it does makes sense from the perspective of a genre that's primarily bullethell, that's confusing as *hell* as someone who's very new to Touhou, or even Touhou players that just don't make the connection and try to apply it to the stitchmaking. I think replacing these sort of attributes with maybe more cutesy qualities that reflect the design of the end-product, rather than its canonical functionality, would be a better fit for player conveyance.
But the core gameplay itself was really fun! I mostly feel that conveyance is the one thing that needs to be focused on for the future.
Also, small nitpick but the alt button keeps popping up my nvidia overlay when I hold it for too long, and I don't know how to turn it off. Consider adding a rebind option since alt is used by a *lot* of external software nowadays.
