Not bad, and it could be even better if you change just these few points:
- The game is dry, it lacks feedback, it would need more noticeable animation when you roll the dice for example (since it's the main action of the game, it has to be satisfying), in short I think that making the game more juicy could really change the game feel for the better. I thinks this conférences can realy help you"Juice it or lose it - a talk by Martin Jonasson & Petri Purho" explains it quite well or "Game Feel: Why Your Death Animation Sucks" which is also very cool
- The game play loop is very repetitive, maybe putting a lot of small battles instead of one big one could give an impression of progression, also the 0.x kills are not very intuitive, we don't have the impression to do more kills, I'm not saying you have to do big numbers in WoW, but just putting numbers but just making it so that we do 3 damage instead of 0.3 would be nice.
But anyway good job
I'd appreciate it if you want to try my game too :)
Thanks!
