I think I figured out what the differences in the die mean (each roll is how many of X action before next roll) which I think is clever, the only problem is you always die in one shot and it starts out with a lot of cannonballs, so you have no real room to experiment and feel the effects of successive rolls. I think it would've been much better if you started off quite easy, that way you can really feel the ship getting harder with each roll and then you have the tension of "oh i really don't want to dash/run/jump here, but i need to or I'll lose a heart" etc. A little bit more clarity would've been nice as well, but overall great concept and solid game!
