simian. interface++ is the long awaited update to simian. interface, an abstract puzzle experience for simian participants of all ages and abilities. There are no explicit rules, no instructions, and very simple controls. Inspired by tabletop puzzles, modern art, and cognitive psychology experiments, simian. interface++ presents challenges that must be solved using pattern recognition, intuition, and experimentation. Features an incredible soundtrack composed by chiptune artist Note! (@n0te_ on twitter) the original simian. interface, now playable in full screen! the new ‚infinite_loop‘ mode, with procedurally generated levels, and randomized music and story content! infinite replay value!
