This is a gameplay prototype that I was working on for several weeks about one year ago. The player is given the ability to warp space by placing two warp anchors anywhere in the world, warping the space in-between those anchors. Space warping also affects physics, which may be used to make objects roll off curved surfaces, bridge gaps etc. Note that the focus has certainly not been on graphics.
Like previous demos, this prototype was built on top of my engine/framework/sandbox called breeze, using DirectX for rendering and PhysX for physics simulation.
