One thing to note:
Lowerdash is a superset of SmileBasic!
Loading a background is the same in Lowerdash as SB:
'''
BGLOAD 0, BGDATA
'''
With Lowerdash, you might make a module "Level" that does that same code in a method 'start' that also sets up coins and stuff.
Later you could just write:
'''
curLvl = new Level('level name')
curLvl.start
'''
