Mighty Fin

Description
The player controls Fin, a fish on a tour of the world. He's picked a budget package however and all sorts of dangers need to be avoided with your precise timing.
The game was originally released for iPhone and iPod touch and then iPad soon after but has subsequently been removed from the App Store. It can only be played now in a limited form through a web browser.
Players touch the screen (or click / hold the mouse) to dive and let go to control Fin through the sea and air. To gain points, bubbles need to be collected while avoiding obstacles. Touching them ends that round and the player will need to start again from the beginning of that level. Certain bubbles give more points than others and so are generally harder to collect.
Costumes can be collected during play or unlocked on the completion of levels. There are also gold medals to achieve. A global leaderboard once kept track of players' scores.
