The idea of a turn-based battle where hiding is a mechanic fits the theme nicely!
The fight UI is a big block of text right now, which makes it hard to follow what's happening. Things like HP bars and buttons for the actions would make it a lot clearer, and the panel could disappear outside of fights. When the game loaded I also wasn't sure there was a game at all until I pressed WASD, so a small "move with WASD" hint or a clear player character would help. And I won fights by pressing 1 to 4 at random, so making the choices matter more would add a lot!
Keep it up!
