For info, I had some problems after installing the version 0.14.0maemo0 from extra-testing.
This was the first time I ever installed it. And after installation, I click on the icon and the game was not launched. Then I rebooted and retried. Still nothing...
I thought I should launch it from the terminal to see the error message : went to /home/opt/wagic and type ./wagic
and then it worked.
I retried the button from the menu and it worked...
I cannot say much as I am very poorly knowledgeable with this kind of stuff... but it may be useful for someone.
