2D world building approach

Hey guys,


I'm an aspiring game developer and I started building my first 2D mobile game in Unity a while ago.

I want to create a sling launching game like Angry Birds or Burrito Bison. My character is already able to get launched and fly through the air and now I started working on the background.

Since I am not very experienced I basically just slapped my background texture in the game and made it repeat itself through the whole length of the level. Somehow I have the feeling that this approach is kind of inefficient and I will have performance problems down the road since the game has to load all textures from the beginning.

Can someone tell me if there is a better way to do it and if I will have problems with my approach in the long run?

Would really appreciate it.
