alternate solution?

I did not utilise the green blocks nor the epsilon at all, just took the clone out from inside the epsilon-plane.

Steps:
- push the red plane with the main room and one clone into the infinity
- step off the main room onto the red plane
- push the main room further into the infinity off the red plane
- use the clone in the red plane to re-enter the main room
- push the remaining clone from the main room into the infinity

That makes the goal just pop up inside the main room.
