added glass, to prevent loosing cube,past the 1st turret, in upper area, where cube funels onto the button.
thankyou to Ele20002, for letting me know.
also, due to items limit.
I had to delete a light strip, over the 1st light bridge.
dark there now.
hope it will add to the effect.

1st chamber: fizzler higher to stop cube throwing. raised 1 tile, to prevent moving cube to other side of chamber, with you on 1 side of fizzler & cube on other side.
the raised fizzler also means doing the solution stormsend's way. thankyou stormsend.
2nd chamber: prevented stormsend's well though out exploit. added 2 flip panels, pedestal buttons, & grating. tested & enough time. but don't delay.
3rd chamber: added glass to ensure player is in funel, when pressing the pedestal button.
