Just remember that the save and load is for the whole state of the game. You can get yourself into odd situations depending on where you save. For example if you give the player options for disabling and enabling music, etc... and you save those settings, then the next time they load they will be where they were when they saved that setting. I tend to put a on load goto layout on there, then I can always send them back to the level select screen, etc... when they load the game. In your case that may not be needed, just be careful where you are calling the save game action.
Also any info that happened since the last save will be lost when you load.
