I'm beginning work on a demo project that, when done, should accurately mirror a real WarioWare game. Many others have tried to create something along the veins of WW but I believe they have failed. This project, however, will be tough; it involves a lot of ActionScript, something I do not claim to be an expert on. I'm using tutorials on the site to assist me. If you have any (helpful) advice, you're free to give it to me here.
This demo project will have six microgames, one of which being a boss game. Once the demo is completed, I am considering doing a full stage worth of microgames. I have high hopes for this project. Let's just hope they don't fall on my head and kill me.
