I enjoyed playing this. Pretty addicting game. Having all the different weapons and having them vary every time after you used all ammo plays really nicely.
Gameplay wise what needs tweaking in my opinion is:
I dislike how everytime your ammo is gone and you reroll the dice, you have to reselect the die / weapon from the menu. Having this selection as a seperate button and having Space default to the current weapon or die you have (or perhaps just the next one, in case you completely used up the current one) would make it so the gameplay is not interrupted each time.
Further the rolling of the die seems to take too much time. I honestly feel like this could be a good mechanic or a bad one. Running away and trying to dodge while the die rolls can be intense, which is fun, but it also just seems too long to me.
The art does its job, and the music works really well.
Overall really good game!
