Wow. You made it with just your finger? That's pretty crazy! I really like it.
But I can't answer your question either about the colors. But keep it up! :D
Reviews for "Terraria : Skeletron"
Epic, but its definitely not the 3th OR 3rd. I would say this is the fourth boss people fight, being that they fight the Eye, the Eater/Brain, AND King Slime before Skeletron. sometimes it is third if they don't get a slime rain, but I fight it in hardmode myself.
It is awesome. And that is all that matters. Also the color don't seem to do anything.
