I'm going to run out of games.
I have some rough memories of an indie game involving non euclidean spaces for some "smart" experience. If memory serves it was going to be presented to (perhaps) IGF or something. The author made a youtube video where he made up an terrible acronym (like X.S.O.A.N.H.O.E.A.T.H.F.P.S.) involving the puzzle elements and the geometry factors. Graphically speaking it was fairly simple albeit polished.
I understand this is very little, do you recall something about that?
