Hi,
I think that i have a memory leak on animation. Every explosion i create 10 explosion objects, and after some time it is growing a lot, see (521 childrens):

My code to add animation is:
var effect6 = this.groups.underPlayer.create((o.x * GameApp.TILE_SIZE) + (GameApp.TILE_SIZE / 2), (o.y * GameApp.TILE_SIZE) + (GameApp.TILE_SIZE / 2), 'bombFlameSpritesheet001');
effect6.animations.add('default', [, 1, 2, 3, 4], 12);
effect6.anchor.set(0.5, 0.5);
effect6.play('default', 12, false, true);
I have defined TRUE to destroy on finish.
