There is no semicolon (;) key in a spanish keyboard.
To write a (;) with a spanish keyboard you have to press "Shift" + "," (comma). This is not registered by your game (not saying it should) but I couln't play your game because it forced me to press a key that doesn't exist in your keyboard.
This is a really important issue you should address.
P.S: Wow, was the spinning and rotating square thingie a character selection screen? I wouldn't guess in a million years.
