It's an old DOS Mario clone. Most of you have probably played it, but chances are you only played the WIP floating around all over the Internet. The main differences are that this full version has six levels, saving options, a main menu, joystick support, it's a few KB smaller, and two-player capibility. I found the developer's website, and in the link I included above, it has the source code for all six levels instead of the four incomplete levels most of you have played. Overall it's actually a pretty good Mario clone.
It would be awesome if this could be ported. Thanks in advance if you'd like to do it.
