Experimental FPS game Souvenir is, well, a bit broken. It’s a work in progress, though – part of a Design and Technology MFA – and not certainly broken enough to obscure the fact that there’s a tremendous idea in here: a gravity-plane-changing mechanic that pushes into the territory of Psychonaut’s Milkman level, while playing with spatial relations in impossible Escher-like surroundings. The glitchiness of the main mechanic was a little frustrating, but only because I was tantalised by this work in progress. If they can get the bumps in the road sorted out, make the play as polished as the dreamlike visuals, and bolt an end on, then it could be a fascinating experience. You can try it for free on PC and Mac just here.
