I was really happy to hear the Touhou remixes. They fit the game surprisingly well.
The combat is really fun and worked well for me. It looked a little complicated at first, but I picked it up pretty quickly. One thing I did notice in the fights against AI opponents is that some of them seem to react extremely fast. At times it felt like they could parry almost everything I threw at them, while I personally couldn't visually react to many of their attacks in time. I'm not sure whether this is more of a difficulty or readability issue, but the difference in reaction speed felt pretty noticeable.
Most of my issues were with the controls and UI. My PS5 controller wasn't detected, so I ended up playing with the keyboard instead. That was totally fine, but I couldn't find any clear hotkey guide, so I had to figure out the controls by clicking through things one by one. I seemed to be limited to Reimu, though I guess I'm not pressing the right key to switch between characters.
I also wasn't sure which options on the main menu were actually available yet. A few of them seemed to be WIP, so I found myself trying each one just to see which modes were playable. It might help to grey out or label unfinished options more clearly.
Overall, I had a good time with the combat. A little more clarity around the controls and available menu options would make the first-time experience much smoother.
