Thanks mikehive
So its best I have 10 images 10px by 10px than 1 image with 100px for example ?
I mean to create some backgrounds ..
What the best resolution of the ViewPort Size for this kind of game ?
Im using 16:9 / 854 by 480
Can I use 16:9 / 426 by 240?
if I increase to 1920 by 1080 , it will force me to have images larger than I should use in a small resolution correct ?
I mean I want to have a game with a good performance , with nice resolution and that fit all devices .
