Big Stretch is a wonderfully ethereal physics platformer jam game where you're a little round guy with very stretchy arms

Big Stretch is a physics-based platformer made in 72 hours by three people for the most recent Down2Jam, and it's free to download on itch.io. You play as a spherical red creature with two stretchy arms, grabbing parts of the world to fling yourself up a tower. There's no saving system, so reaching the top has to be done in one go, though a glider pops out after a short fall to help you recover.
