It's old school. A group of us beat this back in 2000 at some point... or was it 2001? I got to level 6 in about 15 minutes, remembering different things, and got bored with it
It is really clever. I did beat it this morning, but I got absolutely no work done. So now I must spend the afternoon diligently working on the projects I have stacking up here at work. I should have read the disclaimer and paid attention to it.
