Hey Yoshicat, I played briefly as I need to go to sleep. I would say that it is evident that you put a lot of love into it. I'm looking forward to seeing it grow. Also great music.
The main gripe I had is frustrations with control. At the very first menu screen I thought the game wasn't working because the arrow keys and Enter didn't do anything. There also weren't any instructions on the page on how to actually control the game.
Then eventually I realize it's WASD and Spacebar. OK. Next I had many moments even in these few minutes that I played where thought the game froze, but it didn't, it just took its time. I think that needs to be telegraphed to the player somehow. Like when I took the sword, just nothing happened for a few seconds, and then again for a few seconds. I didn't realize I was in a "cutscene".
Then in that tutorial bit that explains how to attack I thought it was stuck again, but I needed to press spacebar to make the text pass.
