I've been playing this game for 4 years and I've used almost every part of it, so I'm getting bored. I hope that we can create parts ourselves, or modify the properties of parts. I wanted to have a panel where I could create and modify parts, which would make the game more interesting. This is not the same as a "Mod", which I think of as just an accessory, but what I mean by creating a part is modifying it directly from the "roots" of the game. It may sound ridiculous, but this suggestion may be an alternative to "Mod".
