GameMaker, the 2D game creation toolkit, has been used to make everything from Chicory: A Colorful Tale to Gunpoint to the original freeware Spelunky. It's also one of the more accessible ways to make games for beginners, kids and students, thanks to a drag-and-drop interface and forgiving scripting language.
Good news, then: GameMaker is now "free for non-commercial purposes on all non-console platforms" - such as PC.
