Wait, this was made in 1999?! I really am blown away by this! I assume anything from that time period would be bad. You really did prove me wrong! I was amazed at how good the animation was. My only complaint is that it was a bit too short.
For this time, that's excusable. This may in fact be the first great cartoon ever made on the entire Internet. The atmosphere is wonderful. It's such a good use of animation at this time. Not much of a mystery, but still fun!
