Isn't that always how it goes with side projects? You think you'll have time then life goes "Haha! Not so fast!" then backhands all the free time out of you. The only thing I would say is, try to include, either in the .rar or a repository, a text file that explains the motive and goals of this as well as what features you're trying to achieve. It's easy for you, now, to remember what you intended and where to go from there. But months down the line, or if someone else picks it up, they'll have an idea instead of guessing from code. (Speaking from experience... it helps a lot just to have a small "readme" on something sometimes).
