Did it look like this?
Yes! That one. Got all messed up at the rightmost teleporter.
Did you go trough the wall on the right upper side because thats normal there should be a trigger sending you to a secret level there
Wait, secret level? I couldn't find anything.
I got there by pressing (Space) to combine them and I don't recall exactly what happened but suddenly the one outside went offscreen and then I moved down.
