Ehehehh.... I think I'm pretty dumb... ^^;
This was really good, but I agree with the other reviews, the sound and graphics could've been better. About that Myst game, I have Riven, and it's absolutely horrible (more proff that I am no good at these realistic logic puzzle games, I couldn't solve Beyond Time either...). Anyway, the other things were easy, loved the part about Mike Tyson.
I was absolutely stuck on the binary thing. I turned them into numbers, but then what...? O_o Could somebody please tell me how they got a4 b3 e1 c5 d5 c3 a2...? Waugh. The ending was.... annoying... ick. Rrargh I wanna find out what happens!!!! XD Great job overall! :D
