Make me feel old
I could barely click on it in time after ringing the door bell. I had to quit several levels after (with the start blinking off). Some were very good, since they forced you to stop and think instead of going in with "mouses blazing". But this could almost be considered punishment for older people who don't quite have the reflexes anymore to pull it off. Not that I'm taking Geritol and wearing Depends, mind you...
