EDIT: For some reason you can't jump when you play this on the site, at least for me. Downloading it and playing it will work. This is a demo of a new Mario game I'm creating. Use the arrow keys to move and press the Space key to jump. Jump on Goombas to kill them. Don't touch Piranha Plants. I'm using my Super Platform Game Engine as the base for this game, with a few modifications and optimizations., such as a 'solidity table' I created so I wouldn't have to test for each solid object, only for one variable. This demo has only 2 areas, but will probably have a lot more by the time I'm finished with it. The area system positions each object to where it should be. Moving things (enemies) have to have a flag for them, because they move. Luckily, the main work is already done, so now I just have to make new areas and do the positioning scripts for them. This whole program is much more complicated than it looks; there are 58 scripts total.
