I try to make a platform game, but I don't know how. Will someone teach me how to? I'm a noob, I know...

You draw a player, some platforms, you make a system to move the player around the platforms, and done xD

We can solve technical problems, but if you want to make a game, it should be you who thinks about the system, what to do and how to program it. It's more a design issue. Trust me, if you don't try to start on your own then you won't feel it's YOUR game. So go ahead and try to do some basics, look at other people's examples, etcetera. It's easier than it seems.
