Ability to use full screen (Alt+Enter)
Currently there's no possibility to resize the game window to full screen (forgive me if there is!).
Although I don't consider this feature as critical, I'd label it as an important feature - in full screen the
game becomes more immersive and the playability is increased. Someone else may disagree but
I'd lift this feature open for discussion anyhow.
Sorry for slim description but I'd say that this is self-descriptive feature.
