Drag portals wherever you want. Click to change axis. By the way, speed will cap out at one point and make you go slow again. The website does this to prevent lag, and/or the website breaking.
NOTICE PLEASE READ: Because of random issues, You can only go into the blue portal and come out of orange. Sorry. If anyone can help and try to find out whats wrong, please do. The teleportation logic is contained in "Sprite 1". Scroll down to see update log. Update Log Ver 1.1 Made portals turnable Ver 1.2 Made portals look better. Ver 1.3 Added background Ver 1.4 Found out I messed up with the background in the last update and ruined the floor because it is entirely color based, then fixed the issue Ver 1.5 Added new wall texture for realism.
