As you can see I tried :P
When I made the levels and the mechanics It worked for me exactly as I would expected it to be. When I failed at a level it was usually because I was too slow or did not put the teleporters in the right order. That's why I thought maybe people would experiment a bit and catch it. I built the first 3 levels with text just for the introduction, but I guess I didn't explain it clear enough. What do you suggest?
