Really nice game! Feels very polished overall, and I had no trouble with the controls.
I'm not huge fan of having to roll the dice before using it to attack, but I recognize the potential :P
Was kinda sad it ended right when I started getting the hang of it and becoming quicker and better, but that's a jam game for you :D
Very well done! And it's very impressive that you did all this with Scratch, but I wonder what made you choose it as a game engine instead of another one (?)
