I spent 2 days on this game. It only has a rocket (sprite) that moves forward and some asteroids (sprite) that spawn time by time and interract with each other (as being rb2D).
I am using URP in order to create a shader for the space background where stars appear from noise texture.
Optimisation:
Vsync is off
Shadows are off
The only global light 2D
the amount of objects in the scene is less than 10
My phone is Samsung galaxy a20. However I also tried this game on different androids and they still lag there. So it is not for a specific device but I made some mistakes when building(colmpiling) a game.
On mobile platforms the default frame rate is less than the maximum achievable frame rate due to the need to conserve battery power. Typically on mobile platforms the default frame rate is 30 frames per second.
