OK GUYS: while playing SA2B, a pretty old game, I was in this level where you have gravity switches and have to get to different areas to complete the stage. So, I'm in the bedroom, I'd likable to click a button, and fly to the roof with rising velocity, but to survive impact with the roof, I'd need platforms making their way up to the roof. Also server wide and single client gravity changes. BTW: Stage was Crazy Gadget, the best of my opinion.
