Hey hey, you left yourself open. You had all the security, except for the most important one - actual physical access. It's like you build an impenetrable castle, then let the enemy straight trough the front gate, opened door and rolled rug out for them. What you tripping about "I can't do anything"? You could, but it's done, now you can make sure that won't happen again, like you did with setting up a lock on your room. Consider yourself lucky that it was just "some pixels in some game", instead of access to your finances and such(change all your passwords, I'm sure you already did).
