Fishbane (2010)

In this game you play as the amazing FISHBANE, a hero who fearlessly dons a diving suit in pursuit of things such as amazing Golden Harpoons and Fish. If I may give you one little warning: the game isn't easy! It will challenge you right from the very first levels and won't relent. Okay, that's it. Good luck to you! I really hope you enjoy the game. Now go: be Fishbane! Impale your foes; leap fearlessly across chasms; snatch harpoons; RIDE THEM THROUGH THE AIR ITSELF; and finally, be awesome!
