Bottle is a short game which you play as a man of solitude who has been left alone by his ex. In the game as you walk through the path, you see her visions and read the notes she leaves to you. Additionally you can do a few exploration if you prefer.
The game doesn't contain much of an action but has a melancholic atmosphere of a frozen island in the middle of an ocean. And as you progress, you hear some nice piano tunes as well as the sound of the soft wind and some shrubs moving by it. Bottle has no saving feature and can be completed in a short time.
After you complete the game, another mode called "Walk Noir" is unlocked and with it you play the same game but with another atmospheric black & white filter.
