seaching for a game

hello i am searching for a game.
its like portal but you played as a stick man and the portals didn't have coleurs
the hole world was black-white plz people i need a good game like portal cause my computer can't can portalPS. i already tried Narbacular Drop and it suckd d*ck

I don't know what that particularly is but you might want to try portal flash version down at wecreatstuff. if your computer really is that slow then you can download shotgate, a fan made portal game for the C64 made by Konfl1kt. you will need a commodore 64 emulator to play that one
