Auto rotation, Dark Mode, Grid size

[Slim08]

Really like your version of 2048 because it works well on my RG405m 640x480 screen in landscape mode without off screen overhang although I have to force rotate it into said landscape mode with an additional app. It would be nice if that wouldn't be necessary and the app would auto rotation into landscape mode. A Dark Mode for gaming at night that is a bit easier on the eyes would be a welcome addition. An option for a bigger Grid like 5x5 and 6x6 over the standard 4x4 would also be nice.

I appreciate your work
