Nice game, thanks had a lot of fun with it. :)

Btw, I found a bug. When you want to play a new game from the main menu after the credits... It shows the cllock and after this moment comes only a black screen.

I had in my chess game the problem (not reported yet) when you leave the credits and restart the game it don't shows or use the show_widget function. Maybe the same problem here. I use the function call in the autostart-script on launch. But same on keybindings with toggle-widgets.. The credit-screen seems to create it, because it's only after the use of it.
