The key to this game is time travelling. To be able to finish the game you need to utilize returning in time and cooperate with your PAST SELF. So for instance in the first part of the game you need to press both of the buttons next to the door at the same time, to do that, you need make a time travel checkpoint (right MB) go and press the first button(E) then return back in the time (middle MB), now you past self will appear and repeat your previous steps, so now you just have to go and push the second button at the same time when your past self presses the first button πŸ™‚ YES time travel can get very confusing, but you’ll get the hang of it πŸ™‚

W,A,S,D – movement
SPACE – jump
C – crouching (it makes it harder for the robots to hear you!)
ALT, Right mouse button – make time travel checkpoint
SHIFT, Middle mouse button – return in time
Left mouse button – EMP generator (it can disable robots and turrets !)

To play the game you need to download Unity3D web player (the web player doesn’t work in Google Chrome, so I recommend Mozilla Firefox to play the game πŸ™‚ )
