I have to admit I wanted to see the ending and so I rushed a little bit. but I definitely will do them now.
I was a little bit surprised since I've read everywhere this game is really long but my save file says 19 hours and 53 min. played. I owned every place besides of the turnip forrest(which I still don't know how to get there. there are doors blocking my way)
I kinda don't understand why you can't continue once you have beaten the game.
