About This Demo

Who would you go with on the toughest adventure?

Top of That Thing Called Mountain is a two-player co-op 2d platformer inspired by Getting Over It.

Work together to climb the mountain using TWO essential tools: the rope and the air cannon.

Fall Together, Climb Again

Make your way past the parasol and over the big tangerine trees. You two are going to fall. A lot. But get back up and keep climbing.

One Aims. One Fires.

Shoot harpoon rope!

Fire your harpoon at a branch, a rock, or anything that will hold, then swing your way up the mountain. But be careful: some surfaces are too hard for the harpoon to stick in.

Fire air cannon!

You have two shots ready. Blast the air cannon to launch yourselves across gaps you could never cross on foot. Don't panic if you run out of shots. When you retrieve your rope, the air cannon reloads.

Co-op

  • Rope: "Player1" aims, But "Player2" shoots
