That was very enjoyable! Short and sweet (although I was enjoying so much I wished for more levels.)
I loved the ability of being able to scale my character to get to levers or places I couldn't reach. I thought the density mechanic was very unique and the jump and tuck mechanic was definitely interesting. Overall one of the better Jam games I've ever played (that's kept me interested purely because I enjoyed playing it and not because I had to rate it). As a solo dev myself that's only been learning for 5 weeks, I am definitely taking notes with this one.
