Premise: You are a dolphin hired by the US NAVY SEALS to intercept dangerous underwater mines that are being used to covertly destroy coastal cities around the world. The core game is a vertical scrolling shooter where you play as a weaponized dolphin fired out of a deep-sea submarine. Starting at the bottom of a trench and traveling up towards the surface, the goal of the game is to destroy a mine before it reaches the surface by first, catching up with and destroying a mechanized angler fish (a mecha) that's carrying it to the surface, and then destroying the mine with your dolphin. The hook is exploding dolphins. To destroy the mines, you have to destroy the mecha with your dolphin lasers and then slam your dolphin into the mine.

LEFT and RIGHT to turn your dolphin
S or Z to fire your secondary weapon when you get it (it appears on your back)

Notes: Dolphin Squadron is published under the ACPC Productions studio name. ACPCP is a student-run production based out of Burlington, Vermont and was founded by a few students from Champlain College’s Class of 2016. The team was founded on October 20th, 2012 during a game jam and has been working on a few different projects since. Dolphin Squadron will be the first official release, though the game was made by only three members of the 10+ member team. ACPCP focuses on smaller experiences with fun and occasionally radical concepts (gameplay or other). They plan to ultimately expand beyond games and work on films, web-comics and eventually make software for other aspiring and established developers.
