Tiburón Tapón (Cork Shark) is a puzzle-platform-ish (is it a platformer if you swim?) where you play as a shark who has to put corks in holes and turn on and off some faucets, to make the water where he's swimming go up and down, and finally stabilize!
The game has 31 levels, with lots of enemies and other submarine stuff!
Available in English and Spanish.
