The game looks clean all in all, but I have a few nitpicks and improvement ideas:
- The dice rolling feels a litte bit like an afterthought, because it does not tie in very strongly with the core concept of the game
- I really like the shooting sound itself - but it can get a bit repetetive! Maybe slightly pitched versions or different versions of it alltogether would be nice. Also the sound for when an enemy dies feels kind of out of place. I could imagine more of a "spacey" sound for that too, instead of just a "plop" sound. (I hope that makes sense!) I think a subtle sound for the footsteps of your main character, or a sound for when the dice is rolling (thinking of the dice rolling sound in Mario Party for example) would also be really cool!
- The hitboxes of the enemies felt a little bit small, and sometimes they just felt really hard to hit even though I was aiming right at them - but I think it's a taste question!
