The arcade action game follows Derrick, an angry shark who is going on an murderous, underwater rampage to avenge the death of his parents. All the underwater creatures including Derrick himself are crafted by hand from paper and most of the game's backgrounds and ocean flora are also made from paper.
The above video shows the process in which Different Tuna crafted each character and filmed Derrick "swimming" through a papercraft ocean.
The game is currently on Steam Greenlight. It can be purchased directly from the developer's website, and those who buy the PC or Mac version will receive a Steam key for the game should it be greenlit.
