Proprioception is a game that puts your perception and reaction to the test, as you fight the clock to move the coloured markers to their correct positions.
Proprioception (/ˌproʊprioʊˈsɛpʃən, -priə-/ PRO-pree-o-SEP-shən), from Latin proprius, meaning "one's own", "individual", and capio, capere, to take or grasp, is the sense of the relative position of neighbouring parts of the body and strength of effort being employed in movement.
Proprioception is a fairly simple, but quite addictive game that's great for your commute or waiting for the bus, most games are done within a minute, the better you play the longer each round lasts, as you get a time bonus with each score.
You control two colored markers individually with your left and right thumbs, as you try to move them as quickly as possible to their colored outlines, and try to wrap your head around which hand actually controls which marker.
The game includes several gamemodes with different rules, like Blitz mode which is played on a smaller map with much smaller time bonuses, or Dextrous Labs where you score each marker individually, but have to do it in the correct order.
