Thanks for the awnsers.
I will take a look into the long story.
As you say, i indeed not taking the whole wardrobe..
So this makes my question more obvious.. Since memory usage going up once i insert a sprite. Even when i'm not placing it in game the memory usage rises.
So this makes my question complete:
"Does memory usage slow down the game EVEN if you don't add all the sprites in-game at once."
I could have a character which can only run left and right, yet with 100 animation frames that are not used. Yet my memory usage will be 100MB.
Does this impact my game itself?
Ofcourse i can try it out but my PC runs it smooth as always, yet i can only test on a Note 2 which is pretty smooth also..
