Stupid Question

[Zakkorn]

Ok I am not that stupid.

Of course I pressed Esc but nothing happens.

While most of keys work (so at least keyboard is working)
For example "P' pauses the game as it should
And "I" starts or stops the engine.

But "esc" is not working in game, if it should, I dont know what is the exit key.

Esc works in the first menu when I enter the game, because if I press it, it asks me for quit.
