It's a really nice idea! It only lacks a bit in execution (level design, mostly), but that happens during jams ^^
I like that you want to have both high AND low rolls, so that you can make you character better AND the hazards less dangerous. Although, I find putting too much speed on Beanie ends up in trying to pilot a bar of soap. XD
Speaking of Beanie, it's nive to have a little story! It gives the game an identity =)
Very good submission, it has a lot of potential!
