A fun concept! The execution can be a bit awkward in places, as the dice-roll motion isn’t relative to the player, but to the map.
Also the intro, while engaging, took a long time. I get that you want to give everyone a chance to read, but perhaps a ‘continue’ button/key or something would’ve been better than just waiting. (Nitpick/food for thought: … so, is the main character a guy or do you assume the player is? – It not something I’ve dinged the game for, just a thought!)
Still a good atmosphere, as the story continues while playing – it’s not just something slapped on the beginning and then forgotten, which is good.
