Really nice polish! But agree with others that no checkpoints is pretty brutal for a game jam game. I made it pretty far, past some tricky girder jumping and back onto several moving platforms, but didn't make it much further. Nice work! and level design! Also agree with others... what can an octopus do in a platformer that you don't normally do in a platformer? Suction onto walls? swing across monkey bars? Ink blast triple jump? (well squids ink not octopi, but whatever)
