After a question about "cave story beta" was posted on Pixel's BBS he released a set of images relating to a 2003 BETA of Cave Story. In these images it is notable that Quote was originally named Curly Brace, Booster was tall, Balrog was a basic common monster, and Cave Story looked like a different game back then. A request for a release of the BETA was turned down by Pixel as he felt the BETA was too buggy for a release.
