Oh! First jam game I've played that's a typing game (like mine).
I like that the controls are a bit odd. It clears up the keyboard for typing and also makes me feel like I'm playing an old school dungeon crawler like Daggerfall. Makes the game a little harder to play but really adds to the atmosphere (which is great btw).
The procedural level generation is very done well too. I didn't notice any joins or big pauses when playing.
The only thing I'd suggest changing is making the "Saving" notification appear in a corner rather than the centre of screen. Its not really something the player needs to be 100% aware of once they trust that there is an autosave system in place.
