Do you mean a 2D game template? I could make one, but I'm currently more focused on finishing my main 2D game as I'm nearly (70%) done with it. The concept for 2D isn't all that complicated, except when it comes to collision. My 2D game uses a very simple collision system. For the backgrounds, that's the easy part as I've done it for many years in my animated GIFs (such as my avatar).
