Congratulation for the game release.

When you choose the coin system to visualize icons, and you open the coin, then select inventory and close it, the voice "option" will become another "inventory" voice.
obviously you can have access to the setting even from the inventory, but... ok it's a little bug.

I'll wait to play seriously a 1.1 version or a 1.2 i want to enjoy it in the best way possible.

Do you happen to have a savegame of this in action, where it's repeatable every time? If so, would you mind emailing it in so I can investigate? I can give you instructions on how to locate the correct savegame file.

no, in this moment i don't have a savegame. I can make one.
But to make it appear you must to initialize a game selecting the coin, then open the coin and choose "Iventory" and then close it. Then go to the options icon and you'll see it.
