Quantum Conundrum Blind Playthrough: Episode 1: The Fluffy Dimension

Blind playthrough.
Quantum Conundrum is a game that I've wanted to check out for a long time now. I've only seen a tiny part of this from someone else's video, and it looked like tons of fun. A bonus for me, as a big fan of the Star Trek franchise, is hearing the voice of John de Lancie as Professor Quadwrangle.
In this first episode we acquire the IDS device and learn about the Fluffy and Heavy dimensions after an explosion traps our uncle in a pocket dimension.
When you, as a young boy, are dropped off to visit your uncle, you notice something’s wrong. First, he’s not there to greet you. Second, there’s the explosion that happened right as you arrived. And third, the house seems to be even weirder than you remembered it. Now, your job is to find-and ultimately rescue-your uncle, by using his newest invention, the Interdimensional Shift Device (or IDS), to switch between dimensions and solve puzzles. That sofa too heavy to move? There’s a dimension for that! Switch to Fluffy Dimension and that sofa is now light as a feather. Need to get up to a high ledge? There’s a dimension for that! Just switch to Anti-Gravity Dimension and things begin to float upward. Need to make things heavier? There’s a dimension for th-well, you get the idea. Switch dimensions in real time, work your way through the crazy complex mansion wings and rescue your uncle!
