oh gosh that's so exciting- good for you! the most exciting thing is to start slowly collecting jacob's ladders and checking in with isabelle every day to make sure you have 15 consecutive days of perfect-ness to get your golden watering can
my biggest challenge in keeping the town perfect is not leaving random furniture or clothing on the ground in town- more than 10 things on the ground ruins your rating! as long as you keep the same-ish amount of trees and pwps in town and don't suddenly lose all your flowers, you should be fine
again, congrats!! that's so exciting and you must be feeling really amazing rn heh
