 # Description
 
 This script will generate cached sprites and strings for you. As long as you use the same settings, they will stay the same and won't come at a large performance cost. Due to how sprite_create_from_surface works, there will still be a performance hit, but since this is for prototyping, that isn't be much of an issue.
