This was solid. It really nails the PS1 style; a lot of "PS1" games just add a lot of aliasing to otherwise high-poly objects to simulate the effect, but this really looks like it could be a PS1 game.
It was also spooky and mysterious, and I would buy a full version of this in a heartbeat if I could.
Only really complaint is that there shouldn't be a run key, and her movement should just be run speed by default.
