Buildings now have Material Cost and refund for changing the Wall/Floor types!
Also updated the Expansion Cost, making it relative to the current Wall/Floor types.

I sprited down some Underfellas (Underfell by Victheunderfella) #Undertale #Underfell #Undertale_au

Otro Update en DEFCON: Como los sprites/gráficos están DEMASIADO detallados, tome la decision de poner resplandores rojos.

Well I think I've got it sorted?
Expanding Buildings now costs resources.
I'm going to have to do some work on the cost though, they get real expensive, real fast!
