This addictive game is based on a very simple and old recipe. Run around, get the key, unlock the door, move to the next level. In the process, avoid monsters, shoot them if you get the chance, and collect any treasure you find lying around. Levels are organized in several "worlds":
- The timegates: This is the hub of the game. You always return here when completing another level. This world always contains a large number of gates to levels in the other worlds, so the player has significant freedom in selecting which levels to play.
- The western world.
- The fantasy world.
- The space world.
