Depends what the mix up is, but since you previously used local storage to save/load values into variables then using save game should be more simpler now as it saves all variables in one go. Are the default values wrong?
but when I do it this way, it also saves things like the positions of the images, I don't want this, I just want it to save the variables, when I give sprites the no save feature, this time I can't give animation effects.
