Hi everyone. I just finished the Space Castle game which is a free retro style platform adventure game that is similar in playability to the games Metroid and Cave Story. The game is beta so if you find a bug then post a message at its forum or post a comment at the bottom of the Space Castle home page.
The Space Castle source can be downloaded at the download page. Donate to the website by providing a backlink. If you have any questions or you like the game then please post at the Space Castle website. enjoy.
