zapiy: Thanks, and enjoy! I've heard complaints that it's too hard, but I've witnessed co-workers play and beat it. It's definitely beatable What do you mean by running the program in an emulator to create games? If you're talking about libzx, the only way to use it to make your own games is to program them from source code. Libzx is not a "game maker", but rather a collection of source code that you incorporate in your own source code to take advantage of its functionality.Shadowrunner: Thanks!
