I was recommended by someone to get GameMaker Studio, because currently I have version 6.1. So I looked at http://www.yoyogames.com/get, and I'm wondering about the features that the free version doesn't have. Could someone please explain to me what the features listed on that page, and which the free version lack are? I'm especially wondering about the splash screen. Also, will I be able to continue working on my version 6.1 files without problems?
