This one was easy and fun! :D I managed to do it! I forgot the coin on the upper part of the teleport island, but luckily I didn't already use a certain break tile so I could go back and use the yellow spheres to stop me going down so I could get the coin... After that I reached the exit! :D :D :D (...
I seemed to stumble into the hidden teleporter, and completed it.
After that I looked into the editor to see how you did that,
it said "memory access violation".
