This was pretty fun! I enjoyed just the gameplay of jumping and strategically using my jumps in order to make it through the vents.
Some minor improvements: I would say the mechanic of having the dice dictate the number of jumps allowed hindered gameplay more than enhanced it. It just became a bit luck based whether I would roll a six or a three in order to complete the level. As far as the overall theme of the game it didn't make too much sense why the dice was related to the card's movement either. Also, on my Mac the dice was cut off halfway on the screen as well.
I enjoyed the music and the choppy greasy graphics had a nice aesthetic to it. That one slide down was super difficult though, but I did eventually get it! Nice game!
