Arrow keys move the Scratch cat around. Click and drag a Portal to move it. 1 and 0 to fire portals
Many thanks to Valve software, as else the great game we know as Portal would never have been made! However, all the code for THIS was by me, not Valve. The mouse must be TOUCHING a portal AT ALL TIMES to move it. 9/3/14 - made the portal pellets functional: 0 for orange and 1 for blue 10/3/14 - fixed the bug that occurs when shooting portal at border 18/4/14 - Added Portal gun (ASHPD)
