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. The update includes infinite_loop mode, which features endless combinations and variations of the level types in the core game and remixed music, level backgrounds, and story screens. Players who want to test their pattern recognition and reaction time can pursue a high score in timed_evaluation mode. Source: The Developer Website.
