Game Editor is a great, easy to use program once you get the hang of it, with a great interface for 2D games, but I hope it gets an update soon for pc, mac, linux for fullscreen/window choice mode, but also any necessary updates so it can continue to function on the newest operating systems.
I'll see what I can do to post some more videos showing how to create some stuff related to the games I work on in the program, if I have time, to promote it more on youtube, just in case people are looking for: Game Editor, easy to use, 2D video game creation software for pc, mac and linux. I'm finally getting use to C language a little bit more lately, but have a ton to learn.
