I am finally finishing the last parts of the game and can now concentrate on how it looks. I have added some parallax scrolling background images. Each image is placed at a different distance from the camera. Thus the ones behind will move slower than the foreground images. An old but efficient way of making an immersive background. It also adds a cartoon-like feeling which works well together with the 3D art/shaders.
We need to keep the game’s memory footprint small so that it will work even on older mobile phones/tablets. Instead of changing textures I merely tint the background images and alters the lighting to get the desired variations.
