Now i thought the idea of creepers coming from mars whas kinda cool....but why cant they breathe on their own homeplanet? Are they mutants of themselves when maybe their world died? Just thought it was weird that they need oxygen where they come from....but maybe thats why they came to minecraftia? You could remove the oxygen masks or keep em i dont really know just wanted it to come to your attention. I will be looking forward to the release.
