I went back and remade my first map from scratch! Here is a list of improvements:
-The level now has gaps! -It's now raining outside the level, giving the indoor park unique atmosphere -Cleaner and more accurate geometry -Reduced size to match the real location better -Level sounds, adding ambient noise to the level -Level lights shading the level and skater appropriately -New updated textures to look more like the real location
Installation
Extract the mod's .zip file to the data/mod/UserMods/Maps folder of your game directory.
Each map should have its own folder!
Installed maps will show in the reTHAWed category of the level select.
