Hey I appreciate you going in depth like that. I think being able to mark your path is a great idea, somehow I didn't really think about doing that kind of thing. I think it would be cool to give the player a marker to draw on walls. You can escape the minotaur just by running, your speed will be a bit higher than his, and at the moment it's pretty easy to lose him just by going around a corner.
As for the materials, I agree some are not great, I just added a lot for testing. For this demo I didn't have reflections working so materials like the mirror or iron won't work as intended. Also I had a bug where sometimes the outer wall textures were not tiled correctly.
For FOV I wanted to add a setting to adjust it as you like, but the problem with that is the hammer's handle is pretty long and if you increase the FOV a lot you can see the handle go inside you as you swing. The model, I just got it from the asset store but maybe I should try shortening it.
