I?m having performance problems too. I?m using cocoonjs for android, all of the rest are just too slow to even work.
The thing is that with each layout I add the game gets heavier and heavier. Is there anyway to manage the memory usage so it only loads what it needs at that moment or something like that?.
I?m having 12 layouts at the moment including all the menu. And I never use more than 3 layers. I really think this game can?t be smaller but still it runs at 10FPS.
All art sprites were done in PNG24 to get good quality alpha, and backgrounds are at 50%JPG.
The overall resolution is 480x800.
