This is a super easy multiplayer platformer.
So it's a 3D platformer, with online multiplayer and it's super easy.

(Disclaimer: it's actually super difficult and not super easy)

Climb to the very top of the super huge level.
Fall down and... well try again I guess. Maybe you where lucky and able to save yourself onto a near platform. Or you lost hours of progress, who knows what'll happen.

Play alone, join the global lobby or host your own 4 player lobby for your friends.
But let's be real, it's much more fun to see tons of players fall down... I mean climb up the world.
