I've got to be honest with you, it was terrible!
I am pretty bad with Flash, but honestly, I think even I could do better than that! The Graphic's were terrible, you didn't even create those images, I mean.. Anyone can copy and paste images, add text and a little bit of music! It's pretty easy, no violence, which you would expect in a Batman tribute! No interactivity and no Humour. That is why this piece of flash only deserves a 4/10.
