Screen control

I am working on a screen manager for a miniature game engine, and so far I can’t find the right solution for managing screen objects without using a “blob” for each of the screens. Is blob valid in circumstances where I need a list of rendered objects in one controller?

I would consider using the MVC pattern in this situation. Otherwise, if you are not careful, it is very easy to get a bunch of spaghetti code, where the screen code reaches the game code, and vice versa.

I recently encoded something that you might call a "screen manager."
