Thanks Kyatric,
I have read Ashley's tutorial concerning memory saving,
We planned to make a Whack a mole game for Mobile,
For the moment we have 63 sprites (each sprite is 189*292 pixels) and we made a spritesheet wich is 1700*2044 pixels with all the sprites,
even when I import that Spritesheet into a blank project, memory use is already 22,6 mb.
I don't want to reduce the resolution of each sprite because 189*292 is enough small I think for phone and tablet games.
With 7 spritesheet and other stuff we will exceed 170 mb for the project.
What transformation can I do on my sprites before or after spritesheeting in order to decrease their weight ?
There are Png with 32 bits 189*192 sprite wich use each above 40 Ko each.
