So sayeth Jeff Minter himself:
Work-wise, I'm now into the redesign of GR++ for XBLA. I already have it running modified for the different aspect ratio and working off the x360 pad as opposed to the mouse, and I'm changing and extending the gameplay; it'll be a much more involved game than the PC-only predecessor. I'm getting all the gameplay working first then I'll overhaul the graphics; we'll likely go for algo generated 3D shapes rather than the hand-drawn sprites of the PC original.
