WTF? Story is a game made with the Cave Story Level Editor. It's humor and how it continues off of the Good Ending of the Original Cave Story makes it interesting. It's actually very challenging and if you're into that sort of stuff I say give it a try!
Here's a LINK to a forum where you can download it.
Although it's still only a demo and can only last so long. It's still being worked on today and I can't wait for the final release.
Hey teka, GUESS WHO'S IN IT?!
