I understand this is a demo but I have some issues:
1. There's no menu. I can't quit out of the game unless I alt+tab out and click close.
2. What's the goal, what are the controls, where do I go etc. ? There's no instructions.
3. The map is broken, literally. There are suspended chunks of the map hanging in the air, I can walk through some of the walls, and I think I've explored everywhere and found nothing.
Looking forward to updates though, I see some potential.
