Forever Worlds or Forever Worlds: Enter the Unknown is an "adventure satire" video game developed by Canadian studio Hexagon Entertainment and released in 2004. The game engine similar to that used in Post Mortem and Syberia sees the player able to navigate through fixed locations where one can then manipulate a full 360 degrees and click to move to the next location. The gameplay is reminiscent of the DreamCatcher game Beyond Time. In order to solve the puzzles "the player needs to think and experiment a little". Hexagon estimates that the game takes 25 to 30 hours to complete. The cursor indicates puzzles paths informational popups and potential inventory items.
