Hi, thank you so much for your kind words!
I understand what you mean about 'interconnectedness'. Revolutions and Mad Science Lab specifically are both built underneath the main paths of the interior of the park, and there is still scope to put more rides in on top. The Invisible Man ride is directly above the space section of Revolutions.
Regarding Shock, this was actually an unplanned ride. Originally there was a shuttle coaster there, but then I retroactively inserted Shock in. As a result I had to fit it around other structures and rides.
