Wix Games pays homage to Valve's well-loved Portal 2 in this puzzle platformer that sends you on an epic quest through a mysterious facility in search of your beloved... sandwich. Using the iconic portal gun, manipulate momentum, flip switches, and use your environment to your advantage to overcome seemingly impossible obstacles.

Taking its cues from Portal 1 and 2, as well as Portal: The Flash Version, Portal Quest puts you back in the testing lab with a portal gun and little else to aid your escape. There's no GLaDOS, but there is a fun puzzle game set at just the right difficulty. And plenty of science.

A casual portal-physics game that's a well-polished piece with concepts paralleling the Flash version of Portal, as well as other titles like Shift 2 and Cursor*10. But instead of being a simple portal manipulation game, Epsilon explores two other physical properties aside from spatial relativity; time and gravity!
