I found this puzzle genuinely enjoyable and really puzzling, but in a good way. Although, I must say that if you don't press the button to release the propulsion gel beforehand it is EXTREMELY easy to get stuck in the area with the button that unleashes the orb. Other than what I have said, this level is satisfying and enjoyable to a level I wasn't expecting when I first entered, it even feels like it could be an official level from Valve!
