This is one of the best games I've come to play in ages. Absolutely flawless (less the odd dialogue error, which really isn't a flaw anyway), absolutely inspiring, and absolutely beautiful; to you who has brought this to us, and to those who have assisted you in the creation of this Artwork, I do hope that I, along with everyone else who found joy and delight (among tears), get to see more from you (and quite frankly, most of us will be expecting more).
Motor Pool is easy; it just requires some good timing to hit the key. Launch the top valve first, wait a second, then launch the top-left valve. Next, wait a second or two, then launch the bottom-left valve. Launch the top-left valve again once it becomes available, then launch the top one to get the white key.
Also, I wanna apologize for flagging EricS2Tefy's comment (that was the one I clicked I believe); my mouse decided to be a prick and scroll wherever it wanted too and I ended up clicking on it by accident. D=
