Stardew valley is a great relaxing game, with no time limits you can take your time and go as slow as you want. The world, while small, feels alive and that's helped a lot by it's simple but lovable characters who each look and feel unique. Each character has their own story and changes over the course of the game. The art style is clean and pleasant on the eyes, everything is easily identifiable and nothing important blends into the background. The music is simple and relaxing and helps create the pleasant atmosphere of the game.
Although there are some issues, combat can feel very janky and I often find the character never swings swords in the right direction, though that might be me struggling to adjust to a 2d game.
The game is easy to pick up and requires little skill to play. It it sure to take up hours of your time.
