Deep Voyage

Deep Voyage is a collapse-style game in an underwater setting. The base mechanics are extended with many bonuses, anti-bonuses, and powerups. The game also includes a jigsaw mini-game and partially-interactive animated backgrounds which can be turned into screensaver mode when paused. During the game, the player helps a beautiful mermaid to win the royal garden design competition in Underwater Kingdom. So there is also a garden-building mini-game.
