I need to make a game for a school project. Only problem is my Java experience is very limited and I have no idea how to start and what to do.
Does anyone have advice on how to make a simple side-scroll shooting game? As in how to use graphics and how to make the background and what kind of code is needed?
<Added>
I was looking to make it like a jump-and-run game, much like Metal Slug
