Sea Sweeper

Sea Sweeper is an incremental cleanup game in which the player controls a specialised ship sent to clear rubbish from the sea. Each run takes place in a limited ocean area, where the ship sails around collecting floating garbage. The Steam listing gives the playtime as about one hour.

A run continues until the ship’s fuel is used up, so fuel has to be managed with care. After a run ends, the collected rubbish is recycled and turned into money. That money is spent on upgrades, including the ship’s capacity, fuel efficiency and collection speed, which allow larger areas to be cleaned and income to grow more quickly in later runs.

The game’s listed features are incremental, run-based gameplay, ship upgrades and progression, fuel management and efficiency upgrades, and the conversion of garbage into money to expand the cleanup operation. The listing also describes the controls as simple and the pace of progression as steady.
