About this game
WORK TOGETHER
You’ll need teamwork to climb anything at all. Place planks, ladders, bridges and improvised structures to create paths upward, but every addition makes your tower more unstable. Help each other build, or accidentally destroy everything in the process.
BUILD & CLIMB
Nothing here is stable. Construct your own way forward using physics-based building and climbing mechanics. Every structure bends, sways, and collapses under pressure. One wrong placement can change everything.
PHYSICS CHAOS
Expect the unexpected. Your creations are only as stable as your last placement. Watch entire towers collapse, recover mid-climb, or turn brilliant plans into disasters in seconds.
REACH THE SKY
Progress through floating island layers as you climb higher and higher toward space. Each stage pushes your teamwork, creativity, and patience further than the last.
CLIMBING IS BETTER WITH FRIENDS
Play solo or invite up to three friends in online co-op. Work together to build your way up or struggle to survive each other’s “helpful” construction ideas.
