No sound
I thought it was funny, but the lack of sound made it feel incomplete. For some reason, I found it very hard to follow, maybe due to the speed, maybe because of the animation style, or even the lack of sound. I am a fast reader, but the text flashed up and away very quickly and someone who is not a fast reader may have issues.
Adding sound, even just music or sound effects, would make it much better as I felt like I was going deaf.
I gave it a 3/5 due to no sound. Lol, maybe that isn't particularly nice, but in this day and age of flash animation some sort of sound is pretty much standard.
