What are the mod features you...
Haven't played this game but it's not a good sign when the first comments on Google Play are about in game items being too expensive. Hopefully it's doable :)
It does not give you free outside upgrades (decorations, tables, etc), but if you manage the resources correctly you can buy them too, so I gave this game 5 stars. Thank you so much!
