Now all portal combinations work! An early version of an Aperture Science Handheld Portal Device. So far it works relatively well, but I need to work out a few bugs. The biggest problem is a momentum glitch, too often sometimes your momentum is lost when you hit a portal, I think it's because the character senses the ground/wall before you go through it. If anyone can fix it, please contact me. Credit shall be given. Graphics made entirely by me. Yes I know the floating Portal Gun looks funny, keep in mind it's an early version. No, the Companion Cube does nothing yet, I just thought it was a nice sprite to share. WASD/Arrow keys to move Q Fires Blue Portal E Fires Orange Click fires the subsequent portal Mouse to aim. The color of the Portal Gun indicates the color portal you will fire next if you click.
