So I'm trying out multi world stage select, I did 10 stages.... I'm noticing I did one Background for one stage, but it sets the background for all 10 stages... Is there a was to give each stage a unique background?
You have to do it manually. The creator is just a shortcut to give you a structure in which to build your game.
What settings under World Settings should I use for different backgrounds in each world? How do I set the bullet animation to shoot upwards in a vertical shooter? The bullet seems to shoot 4 o'clock.
