Here are my thoughts in real time as I go through the game:
It's not obvious that you can't move until a certain point. I thought the game was broken. Very minor issue but might be worth mentioning in your description.
The throwing mechanic is solid but feels sluggish because the button triggers the animation, not the attack. I would recommend throwing out the dice immediately when the key is pressed.
graphics and atmosphere are amazing!
This is super fun so far. I would play a full game like this if it had this humor and charm.
"That one's gonna leave a mark!"
Lot's of empty rooms :( I want more dice!
Ok... That's enough dice now. I'm invincible!
Overall, fantastic game! Keep developing it and I'll be your first customer :D
