Fish Fillets NG is a freeware logic game available on Windows that challenges players to solve puzzles using two fish characters. The game, developed by Fish Fillets NG Team, is a multiplatform adventure inspired by a paid game with the same name. Players must navigate through various levels by strategically moving objects blocking their path. The smaller fish can only move lighter objects, while the larger fish can handle all objects. However, players must beware of getting trapped or squashed by the objects. The game offers 76 levels that progressively test players' problem-solving skills, with the option to restart levels using the back key.
