is there a way to change the game language?
Mine is set to german (like my OS language), but I found some gramma errors and REALLY want to switch to english.
(I prefer to play games in entlish anyway :))

You can select the language from the main menu in-game: Options and stuff | Options | Language

Oh, this is embarassing :)
I wonder how I could miss it. Thanks.

Haha no worries mate.
The first time I ran the game I got annoyed there was no 'quit game' option.... until I realised it's also under 'options and stuff' :)
