I nearly gave up on this one. I had a lot of fun with all the Cube Escape puzzles until the second half of The Cave which gave me a headache more than once. :D Even with the help of this video, I just couldn't figure out why the engines were no longer powered after collecting the White Cube. It was literally in the last second of skipping through the video again in aimless frustration - I probably would have closed the game and never touched it again, thought it was a bug - that I saw you had to put the wite cube into the control panel to regain power. Omg. Anyway, thank you for the helpful video ;)
