It was made with PAlib, you can still download the source for the game from link in my first post.
If you wish to continue work on it then start by downloading PAlib here http://palib.info/forum/modules/PDdownloads/

Check the tutorials which will show you how to install, compile, and code with PAlib. http://www.palib.info/wiki/doku.php

Also you should copy your post and put in on the forum where the guy actually posted the game. As he is unlikely to see what you said here. http://palib.info/forum/modules/newbb/viewtopic.php?topic_id=4034&forum=9

or better yet just pm the developer

Good luck
