Achievements are displayed on the player menu, under the "Collections" tab, on the "Achievements" tab found at the bottom left. If you own the Steam version, Achievements are displayed in Steam as well, including some extra achievements.
Achievements can unlock specific rewards within the game. Steam achievements need to be unlocked only once, but the associated rewards must be earned separately for each new game.
Unearned achievements appear as grayed-out on the player menu. Some achievements do not display on the player menu until completing other achievements.
Most achievements unlock a unique hat for sale at the abandoned house in Cindersap Forest. In addition, the day after earning "Gofer" (Complete 10 Help Wanted requests), Mayor Lewis will send 500g in the mail. The day after earning "A Big Help" (Complete 40 Help Wanted requests), Mayor Lewis will send 2,500g in the mail. The day after earning "Master Angler" (Catch every fish), Willy will send a Stardrop in the mail.
