I really like the combat system a lot & I think the white health mechanic is really cool, so for my upcoming criticisms just keep in mind that overall I like the game. I like the way it looks a lot as well, the boss arena itself is a visually composed scene and I'm excited to see more areas & characters in the game! Cool aesthetic overall.
Maybe the dagger should be its own separate button instead of a left control + LMB, since it's awkward to press qucikly press left control while trying to wasd around the boss just for the dagger.
I encountered some difficulty with the options, I tried getting it to not run in full-screen mode but no dice and I also tried adjusting the resolution up from the default 1920x1080 but it still used 1080p (see my attached gameplay footage).
I don't like the stomp move in the demo area at all. I think the playable space is too small + the playable character too slow to properly avoid it (especially the large stomp) and I think I still got hurt by it even when I tried jumping it. I do like its visuals a lot however, it's just a pain to play against in the space provided. Also I'm a little iffy on grabs. Maybe it's because my resolution got goofed, but it seemed like they were hard to see.It might just be that I just started playing this game so I'm not used to it but the timing on the boss red attacks felt pretty slow, I've included the footage of my playthrough at the end so you can watch for yourself but I think I missed most of my parries because I was too early. IDK, you don't have to listen to me cause I'm kinda salty that I didn't beat the boss so, eh. Still a demo but I'd appreciate future attention to those attack animations--I think some are telegraphed & delivered well, however some are telegraphed well then delivered too slowly. However, I was mashing pretty hard , I probably would've done much better if I played more respectfully.
Anyway, I did like the gameplay even though it's very unforgiving & I'm a salty loser that didn't beat the boss! I recorded my playthrough, I hope it helps:
