It's okay. Do you think copyright is the problem. I noticed that's the main problem. People don't put copyright and it gets taken down. I put the copyright for me and Nintendo one time in a Duck Hunt game and SmileBoom didn't care. Then again, maybe I'm just super enthusiastic. I mean, It's Easter!
