First thing first: thank you for taking the time to make a step-by-step tutorial. It really helped to grasp all the mechanics of the game. The game was quite difficult to me, probably because I'm not extremely used to first person camera, but the fact that the overall gameplay is well polished made the experience worth my time and fun!
I like how you pay attention to details to make the game feel better. For example, I think that the colored dice are perfect to indicate the different weapons since they are well recognizable, and I would say the same thing for the big and easily readable numbers above the dice after rolling them. Good job!
