Let's see what I'm talking about. Please, be aware that everything you see here is still strongly WIP.
The base interface is quite simple: you can move around the world with the usual "first-person shooter" controls: mouse and WASD. Nice and easy. When the crosshair goes on an object, you'll see its name on the screen. Then, pressing the left mouse button, the interface will appear.
Anna Interface has three verbs: Examine, Pick up and Use.
Moving the mouse pointer on the preferred verb and releasing the button will execute the command.
Pressing "I" you'll get in the Inventory, where you'll be able to do all the classic point-and-click operations: combine objects, use the objects with the environment and so on. Very nice and easy.
Something interesting in "Anna" is that you can pick up everything that looks like it can be picked up: you can take whatever you want, even stuff which is completely unrelated with puzzles. Using the inventory commands, you can also remove them from your inventory: the object will fall on the ground, where, if you want, you'll be able to pick it up again.
Doors, closets and drawers are opened in a natural way: when you see the "hand" icon, you can grab an object pressing the right mouse button and move it with a natural mouse movement. This has been done to increase the phisicity in the world and give a little more the sensation to be there.
Hang on because we're going to have a set of screenshots very soon! To ease the pain, here's one:
