ciemnogrodzianin: For Spelunky - you can easily check GOG keys here. Activation is two-step process and you can check validity and expiration date and go away by clicking Cancel leaving the key untouched.
By "here" you mean the redeem page? The link doesn't go anywhere :O Haven't played it myself yet, but I only heard good things about it. And it's definitely goofy as hell. :D
