Portal, is it worth trying?

[Nay_Sayer]

It's FPS, no thank you.....

Its as far as you can get from a FPS. It's a first-person puzzle game that really gets your noodle going.

Highly recomend

You shoot portals with the gun you saw; for example in one puzzle you see a cube that needs to be on a pressure button to open a door, you cannot reach said cube so you shoot the first part of the portal at the floor under the cube and the 2nd part of the portal at a wall near the button. The cube falls through one hole and out the other where you can pick it up and use it.. (the game explains the mechanics of how to do this in an opening tutorial)

The puzzles get increasingly more challenging and involve momentum physics and lateral thinking.
