This is insane! I've already spent like 10 minutes combing through, finding all of the neat references and easter eggs. There are just too many for me to point out, and there are some that I even recognize but just can't remember the names of. I LOVE how you have the level icons around the border as well. Looks like pretty much everyone is here- holy smokes. Even the NG soda machine! This is so crazy and I absolutely love it. Funny side note, the first person I saw when I zoomed in was none other than Waldo.
