Grab

About

GRAB is a multiplayer parkour game. You climb, slide and run through levels to make it to the end. But don't fall and don't touch the lava! It's a fun multiplayer experience to try and finish levels first, showing others how it's done or making levels together to share with the community.

The editor allows one or more players to work on a level at the same time, and any player can jump into play mode to test a section at any time.
