I had them come in and check out my room, make sure it worked, and offer ideas on how to improve the room. I did this for the Spinner Blitz as well, where ChernabogForever and Silhouette were very helpful, though in that case, the room they reviewed and tested was much closer to what you saw. In this rooms case, they (Especially Silhouette) rebuilt much of the room. It helps to have 5 people going at your rooms trying to find flaws, as opposed to testing it once, and hoping you tested well enough to find all the issues. Don't want repeats of the chair race incident.
