I regret almost everything about my island but don't have the guts to reset because I've collected so many resources and items. So I bought a new copy of the game to start over with lol. This time around I will be way pickier about my native flower and fruit (hyacinths and peaches only this time) and will build villager houses WAY slower. I'm also not going to use amiibos and will just keep whatever the game gives me.
I'm a little disgusted with my island because it feels artificial with all the amiibos I used and the layout is so bad and I can't fix it at this point. So it will be nice to start over with a new copy.
