Hi dunc. Just played both of your Rollaround levels. Nice idea for a puzzle, Though I never used any of the red spheres and only needed to get the green sphere Gen going to cover some buttons, I used the metal box to move spheres around also used it to cover the last button, I did both levels the same way, and Loof was just a spectator, Good concept but didn't need alot of stuff, Maybe that's what you intended as a red herring.
