please how do i save after building my memory palace

Your palace saves automatically. No need to take any specific action. There's no save button or anything like that. That said, please note that the text panel does have an edit and save button. So if you click EDIT and make changes in the text panel, you need to click on SAVE to record those text changes.

Also, I noticed that you haven't selected a user name yet. To do so, go to the account tab in the MENU and select a username. Hope that helps! Let me know if you still have any questions. :)
