Weekend Hotfix

Man what a ride. Published the game and from there on several bugs had been reported. So instead of chill and beer it was code and beer this saturday. What is fixed:

• Endscreen now shows the name of the winner
• The game remembers your last used names
• You have super cool default names if you forgot to choose some yourself
• The pawn has his animations back again
• Promotion now works again
• And if a pawn moves two fields the attackable field for en passant does not block the movement of other pieces
