Lost Labyrinth is Open Source! This means you can download the sourcecode the graphics and the sounds that we use to create the game.
BUT you will not be able to compile it until you own the Purebasic Compiler!
(Which you can get here: http://www.purebasic.com)
And this is a commercial program. We are sorry for that!
BUT if your idealism of only using selfcompiled code prevents you from playing the game its your fault not ours!
