Really nice graphics and atmosphere! I had the same impression as the other commenters that the controls/movement could have been more responsive though. I was also confused when I couldn’t enter the door despite the UI prompting me to, and had to check the comments to realize it’s because I didn’t kill enough enemies.
I played this on stream today (recording here) in case you’re interested in watching someone play your game. Despite the mentioned issues, I think there’s a lot of potential here if you ever find the time to polish it!
