Hi there, I’m sorry you had some trouble there. I’m glad you didn’t quit however. As for allowing the player to save whenever they want, I’d rather avoid it. Putting a system like that in gives players a chance to exploit certain things such as fishing or mining chances, or really anything that is chance based. Forcing one save per day tends to prevent that. I will add it to my list to maybe make some sort of prompt that informs the player that the game saves at the end of each day.
As for the map issue I’m not sure. I’ve never heard of the map key in particular freezing the game. When you say freeze do you mean actually froze, like the whole program stopped? Or did you just get stuck in the map screen with no way to revert. A good gauge of that would be for instance if you could still hear sound effects after it happened. If that was the case then it was likely a bug I can check out. If literally every aspect of the game froze it may have been your computer.
Also don’t worry about your English you sound fine. Far better than I would sound if I tried to speak Spanish, that’s for sure.
