Succeeded to work on linux wine.
It took me a pretty long time but I cleared it. I haven't played Sekiro, so I.'m not sure I can give very good feedback on the gameplay. I had a lot of fun though.
The camera was kind of laggy and stuttery, and combined with the lowish fps I was getting, it didn't feel very good to look at the character move. During the tutorial fight it also bounced on the bridge pillars in a jaggy way, but that wasn't a problem during the real bossfight.
Art wise, I really liked it, although obviously some parts weren't as polished as they could be. The way the boss blended between weapons was pretty interesting and made for a fun fight.
One thing that could help is some more noticeable feedback for getting hit and hitting the boss. Especially at first when I was figuring out the game, I was often unsure if I had successfully dodged/parried an attack, or if I landed a hit, so I was constantly checking out the health bars. If it was easier to tell without looking at the UI it would probably help with immersion and flow.
Oh, when talking to both NPCs, X didn't close the dialog, so I had to alt+f4 and reopen the game.
All in all, especially considering how ambitious of a project this is, I think this is a really great submission.
