After about two weeks of work on this, I think it's ready for release.
Dark Defender is my second attempt at making a game with elements similar to an old arcade. In this case, as the name suggests, the base for this game is... Defender. I wasn't feeling very imaginative, sue me.
There are versions of this game for Windows and Mac OS, and if you have Google Chrome, you can also play within your browser.
Remember, this is a beta release and I do expect there to be inconsistencies. Any reports are appreciated. I am really hoping this system will work well for everyone.
