😱 Thank you so much for your report!
I must fix it asap 🙏
Edit: 🤔 Actually... I didn't find the bug where last name is removed. Maybe it's accidentally fixed ;u;
Well, I recently updated the game, if you played in a previous version, could you please check if it's working?
About the background menu, it probably has incompabilities with some screen sizes :p For now, I left on the settings an option to disable this effect.
