Why would you complain
Your review on the recent flash, "I love the HALO world" got me interested in this collab you mentioned. But if you had any common sense at all you would know that having a collab of people doesn't always mean dick jokes and more dick jokes plus a few bad animations will top that of one artist who took the time to make something much better. Sure, Greenfrost6 had sprites throughout, but anyone on this site can clearly see that more time and creativity was put into his work more so than a bunch of people trying to get a cheap laugh with an hours worth of animating.
Don't complain when your "hard work", in reality, only took 20 minutes.
