Have YOU ever wanted to participate in a Sleep Study - slash - Parapsychic  Limb Manipulation Trial? You have!? That's incredible! I wanted to make a game about that! Unfortunately, I made this one instead.  

A first-person grappling hook platformer game for keyboard and mouse.  You can collect orbs if you want.

WASD Movement,  space to jump, camera movement driven  by mouse movement, fire by holding-and-releasing the  right-mouse-button (the 'RMB.' )

I had fun putting this together, even as rough as it is, and I hope you get some entertainment out of it too.
