Port Valley tells about the elections taking place in the port town of the same name. You can observe events from the perspective of 3 main characters, each of whom has their own story campaign. The protagonists are quite ordinary people who find themselves in incredible events. Among them, for example, is a lazy pizza delivery man and a plumber with a mysterious past. The routine of their daily lives is disrupted by circumstances, forcing them into a story of revenge and political conspiracy.

In terms of gameplay, Port Valley is a point-and-click quest. Characters run freely around locations, chat with NPCs, collect and use items, and solve puzzles. This is interspersed with situations more unusual for the genre. For example, cutscenes, escaping from cockroaches and even fighting them in JRPG style. In this way, the game shows its conscious humor and slightly breaks the fourth wall.

In addition, the NPC life is a feature. There are 3 candidates for mayor in the city and several dozen other residents, each of whom has his own goals, and will strive for them regardless of the player. With multiple storylines, the freedom of the characters creates opportunities for replayability. Only by running through the plot several times will you be able to get a complete picture of what is happening around you. Adding reasons for replaying is the presence of 3 different difficulty levels.
