Ok, I have a ton of ideas for a huge map called the Superscape. It would probably have to be multiple maps...
Note that all this should be done with a Blocko approximating the size of a human.
But:
Fire area: Large cave network with lava, called Magma Mountain
Podoboo Peak, a Volcano Caldera, lava filled with various platforms above the lava, roughly the same height, using the lava from Slate Lava which is scripted to kill, and with a second version with different height platforms for a flood game style
Fiery Falls, a lava falls down a mountain, with a massive lava pool at bottom called Lava Lagoon, Falls intended for lava boat races, Lagoon with stone platforms in same style as Podoboo Peak.
Preferably put the entire Fire area in one map.
Ice area (note that this is a lot less finished, concept-wise)
Freezie Field, an icy field, idk what for
Golden Forest, a forest on a slope off the side of Freezie Field, with snow-covered trees, preferably with collision for a snowboard race off the treetops.
Glacier Gulch, the valley at the bottom of the Golden Forest slope, valley sides become a canyon
Iceberg Isles, working a lot like Podoboo Peak but when the player enters the water they take cold damage or die
Lubax Station: An eight sided space station, I will get the pics up when I get the chance, i have it all sketched out, but for it to work I need someone to release a diagonal JVS sliding door...
Bone Bridge and Cobbler Isle: one island in the middle of a huge pit, which kills upon falling in, and one large bridge looking like its made of the bones of a giant creature or perhaps tons of normal-sized creatures. Preferably a second version as well with eight such bridges evenly spaced around Cobbler Isle.
