Upstream is a visual novel game where you are looking for your missing friend in a dense forest. However, when you find clues, you start to see beings who questioned you if this disappearance was really accidental.
The game has a pleasant atmosphere and is emphasized by the sound effects, making the use of headphones highly recommended to make the most of the experience.
The game is short and has little interaction, showing that the focus is really on the narrative. The pixelated images and the gray palette reinforce the atmosphere of terror along with the sound.
