It's best to assume that we're all overly paranoid. I'm not going to download anything from your site unless you can prove to me that it's completely harmless. The best way to do that is to post code and ask a detailed question about that code here. Otherwise, you probably won't get much help from anyone smart enough to be paranoid.

That's where you make it smaller so that it's suitable for posting. You know, cut out all of the fluff so that just the necessary stuff and the errors are still there. Most of the time just doing that helps you solve your own problem without posting.
> warning C4996: 'kbhit' was declared deprecated
That's a Microsoft-ism. In their infinite wisdom, the creators of Visual Studio decided to mark random functions as unsafe and deprecate them with this warning. In the real world, nobody cares, so you can ignore that warning.
> error C2561: 'Game::timerUpdate' : function must return a value
This is pretty self explanatory. You say that timerUpdate will return bool, but you don't return anything. Either return true or false, or change the return value to void.
