Thanks for answering.
Ook, I'm going to review a little more about debuuger.
On the second point, already includes all the necessary objects in each layout to avoid lag.
The draw call in my game if I see it in the debugger is between 3.3 and 4.5. (that's bad?)
And in the background I have a farm background: size 1363 width and 302 height (tilebackground)
Another of height mountains: 836, widht: 371. (tilebackground)
One of clouds height: 2000, widht: 439. (tilebackground)
And the sky height: 32, widht: 32 (tilebackground)
Do you think I exaggerate in the background? Are the images too big or too large?
Or would it be better to place them all in a single large background as: 2048x2048?
