Thank you for your review.
The room is not for full double jump, to pass that room you need to jump again just before you are about to fall in the green acid on each platform.
Jump works according to the hight of celing in the game.
It’s little bit hard i know but with practice you can do it. My record in game is 5 min and 37 seconds. If you complete it then definitely tell me.
btw, thank for review :)
