That's effectively unfortunate to compare your design to OOP because we tend to have different opinions of what OOP is. If you see OOP simply as message passing and polymorphism then your "all-e" and "renderer" functions just reimplement these ideas (as opposed to have your function simply assign different values to your data). Why isn't your "render-player" not a method?

It would have been interesting to go into more details about the CES design. For example, how do the components interact with each other? How is "position" updated when interacting with "walker" and "jumper"?
