Okey I got it working, but I gotta say that the movement is very counterintuitive, I got the portal appearing but for ages I forgot to move forward, was so used to just pressing W to make sure I wasn't hitting the edges and when I started moving forward it just dropped down and I lost.
But yeah the movement is working, was just a learning curve for sure. Maybe better indicators needed, but yeah got it working! Thanks for the video!
