Routes- Today i died

It sounds like you jumped in without reading the docs, or at least the right part of the docs. The user guide tutorial takes you through a complete simple app.

The "default controller" is the name of the controller to look for if a controller is not specified in the URL; it is *not* the name of a subdirectory, nor is "public" the location of any controllers, nor is it a routing specification.

What does go in "public" is the "front controller", index.php. This is not a true controller - it is some PHP logic to bootstrap the framework and trigger the framework's routing etc. This is standard practice. I know of no framework which behaves the way you describe
