If you liked Portal and Portal 2, then you will like the Turing Test. It is similar to Portal but without the Portals. You go from room to room solving puzzles like in Portal. There are 7 levels with 10 puzzles on each level (with an optional challenge puzzle on each level). Look for the door that says Restricted Area. Have fun.
Sometimes lost is where you need to be. Just because you don't know your direction doesn't mean you don't have one.
