Return Portal is a puzzle platformer where you must collect the key(s) to unlock the gate in each level with the help of your trusty teleporter. Drop it down in the correct spot so that you can jump to it and get through obstacles which you never would've been able to pass otherwise! Teleport out of holes, through moving walls, onto platforms and so much more! Take it slow and really get your thinking cap on, is not as simple as it looks!
