Sorry, as it says at the end of the page, "Unfortunately I couldn’t finish it in time for the Ludum Dare, but I don’t want to throw the code away so I’ll keep working on it."
So there's no actual game on this game yet. I may go back to it someday, but other jams came since then and I ended up not returning to it. You may check my other games, though, they do work on Mesen :-)
