Its portal themed use wasd to move mouse down, to create portals sometimes if you do not have a second portal, your second portal goes to your first click at desired location to make portal b click at desired entrance to make portal a also there is a glitch where the portal sprites are rendering wrong and the outline has variants Portals go to your mouse! Portal Cursor is swapped lol dont put portals against the wall they clip you into the wall if the portal cursor is red, do not make a portal there this is because i cant figure out wall collison! oh wait you cant if it is touching a wall haha anyways now you know aperture technology cannot be used inside of a wall, though im not sure why you would do that. well the infinite portal thing works also HAHA LOL I ADDED MY OWN BOX JUMP by that i mean you can fly using the up and down arrow keys, it looks like a turret jump from the original portal 2 lol press space or enter
with the hd mod its not all that useful with old timey mode
