In the pc with chrome the movements of my game go well, but play it from my smartphone not goes well.

I saw that the assets of your game are pretty big, for exemple oscuro is 1400 x 1050, I think you should reduce it's size in the image editor, then scale it up in the layout view, since it is a gradient, the loss should not be noticeable too much
Also sprite7 is too big, you should separate it in multiple smaller objects
Star could maybe be smaller
bg1 bg2 and bg3 also take some space
creditos could be remplaced with a Spritefont/9-patch combination but that is not the culprit I think
Explosion1 is too detailed I think
Particles is 250x250, I think it is too much (it is empty too?)
Sprite 4 could be smaller maybe?
I think all of this is your principal issue right there (might not be the only one though)
