That’s a great idea and was very fun to play ! The control felt nice, maybe just add a little bit of coyote time. And the dash feels more like double jumps really, and you probably could just bind them to the same key.
I think you could expand on that idea by proposing alternative routes you could take at some point based on your dice roll.
Anyway, great stuff, I had a blast playing it! This is a strong concept for a very good game!
