I managed to decrease the amount of memory by converting sprites to tilebadgrounds and reducing the quality of others.
This is the result. And even so, at times the game gets to use 1000 mb.
It is very sad to have to reduce the quality of my sprites, when the game works perfectly in C2.
Also know this problem because they created options to manage the memria, but they are completely useless.
I'm sorry for the enrage.
