Finally, here is "projex", my Valve's Portal mod. It's more of a skin rather than a real-game Mod of Portal, with additional puzzles. No scripts and or codes, I customized the MOD to adjust the look of the game and create basic puzzles for Level Design.

I would like to thank Jeffrey Arriola for the English assistance and aleng that allowed me to use their font for my title. [link]
