like red said i finally solved this one. i hate that i looke at that screneshot. but it still was like how? finally figured it out

jandlml and I just solved it. I thought it was OK, but it's not very clearly stated, if you know what I mean. The sensible goal that worked for me was to keep a connection to the starting room so I could do the last step by simply respawning the cube (suanpan's picture) , but that turned out to be either too difficult or impossible... Needs refinement, but the over-all concepts working in this puzzle are really good. The timing was an emeny to my reasoning; I didn't consider I could do everything in a single sequence until of course jandlml showed me how it worked.

ok i can get the cube to the exit but not the laser cube. really stuck

I made a new map with this way.I hope you will like it.
