Razor Rocks

Overview
Your task is to build a massive coaster-filled park in amongst Razor Rocks.

Razor Rocks consists of a large desert area that covers the majority of the overall land tile, with 10 large rocks abruptly protruding from the ground. Each rock is about a hundred meters tall, which makes leveling nearly impossible. The objective is to build 10 different roller coasters with an excitement rating of at least 6.00. The rocks make building pre-designed roller coasters difficult, so many roller coasters must be custom designs. Though there are 10 rocks, there is no need to build a coaster at every rock.

Other Notes

 * This is the first scenario in Loopy Landscapes to have this objective.
 * Also sometimes after you build your ten coasters, the excitement may drop, so try to keep the excitement at least 6.30
 * It may take five minutes for the game to realize there are ten coasters in the park with excitement ratings over 6.
