Great execution on a stealthy Roguelike. Particularly effective use of status / awareness indicators on NPC's. I also dig the unique setting!
Small bug (though you may have already fixed it): When my inventory was full (all nine slots) I couldn't select the ninth item.
Overall a fun experience that changes the roguelike gameplay dynamic by making you avoid / take a lot of time to deal with hostiles.

I was reading up on the Osnowa framework and then realized you are the creator as I was playing through this entry. I'm working on my own ECS engine in C# and had thought I was super clever coming up with component-states for AI when I came across your (extremely smooth) implementation. I'm still a Unity novice, but I got the Osnowa demo up and running and am considering using it for my next project now that I've seen what it can do in such a short time.
Cheers!
