This will be my first Corona game. I am familiar with programming but not much about best practices regarding game design.
I am making a top down game (for mobile devices) where the player has to travel along a path and get from the start to the finish with enemies along the way. The camera will follow the player as they travel along the paths. There will be boundaries so the player can only travel where the path (or paths) lead to.
I am planning to make several levels (20 to 30) which will have different paths.
I am planning to make one large background image for each level.
My question is 2 part:
1. How do I go about figuring out how big the background image should be? I'd like the levels to only take about 5 or so minutes for the player to travel from start to finish.
2. Is the best way to make a separate image for each level? I'm not sure if that will require an excessive amount of space or is that standard for games with multiple levels?
Any advice would be really appreciated.
