This decision will put away some of the "roguelike" idea behind the game, but I found that the very restricted view due to the screensize is enough constraint.
Instead of the fog I now added a bit of darken out to the edges of the screen, which gives a bit of an impression that there's a lightsource at the players position (like wearing a torch).
A very positive thing is that the fog of war slowed the game down a bit, which runs a bit smoother now.
