Aw, cheer up Plugabugz! It wasn't bad, people just like to complain. I'm sure with this as experience you will do extremely well with your third game!
I cracked Thatguy's code, it is how I knew he was Red.
Don't ask me how I figured it out, as that's a secret. Here's the message from his PMs:
1. I'm going to take you down and drive a blue shell up your silly gigantic snout, pig-face!
2. I'm pretty sure you've hatched an idea :p
3. Chill, chill.  Don't get so eggxited!
4. No, really.  I do plan to eggsecute you, you should understand.  I truly will be the punisher.  Mark my words, you're in hot water now!
5. I may be overeggsagerating... Maybe.  I might not crack so easily, despite you ceaseless bickering and badgering. Any reason why I should bring you under my wing?
If you take the letters I bolded and put them together it reads "I'm a tomato". And tomatoes are red so...
