Interesting game in concept, but I think it has its issues in the UX dept
While new dialogue with the wizard let me know I was making progress, I didn't feel like it. All walls and floors look the same and there are no environmental clues apart from torches and basic level geometry, and so finding the right path always felt like half-guesswork. (And was especially frustrating when I died and had to backtrack). Also because of the lack of vfx for (dis)appearing walls, combined with the vertical camera axis lock, it got pretty disorienting at times.
But the wizard was a good idea to guide the player, and frame the setting because without them, the game would be so confusing. But it's not, and that's good!
I can definitely see your vision with this game and like your interpretation of the theme!
