Very cool! Reminded me of those Pen and Paper games. Your implementation of a turn based combat system with multiple attacks and effects is impressive! Not to mention it's fairly balanced! I noticed a couple of bugs in the WebGL version, but noticed you mention those go away with the .exe version (gotta love WebGL...).
Your game is also a very creative take on the dice theme - I haven't see anything else quite like it yet in the jam, so nicely done there too!
Overall, great job!
