Interesting concept, for sure! I like that you couldn't just use a specific ability right from the getgo, and had to rely on the roll of the dice.
The things that I think didn't work so well were the grappling hook. I never got that to work. Nothing ever fired out or grappled to anything.
The dice ability is interesting as well, but maybe would be better as a special ability you can use as a get out of trouble a limited number of times per map. I never found myself in trouble in a such a way that it was of any use. I think I got it to fire at a cube once or twice, but then the mini cubes also hurt so that is kinda awkward.
This would be a great concept to continue on with! I'd love to see it after it's had more time and polish!
