Ok so personally leveling up is quite difficult, I really havent tried hard, but for everyone who is trying hard, just know that pretty much half the people on PMC who are very high levels just post things that are almost the same as others. The key to leveling up is to just make some map that you built on your own, or with some friends and just make sure it has enough cool things to keep someone entertained for like 10 minutes and it will be downloaded.
