This is a game I did at the Global Game Jam in San Francisco, a project of the International Game Developers Association (IGDA). The structure of a jam is usually that everyone gathers on Friday afternoon, watches a short video keynote with advice from leading game developers, and then a secret theme is announced. All sites worldwide are then challenged to make games based on that same theme, with games to be completed by Sunday afternoon.
Basically– 48 hours to make a game. Start to finish, soup to nuts, by Sunday afternoon it’s “pencils down” and show what you built.
Our theme this year was “oroboros”, so we made a game that had a “looping” boss.
Players control a shark who becomes stronger in order to defeat the boss shark. Once rival shark is defeated, the player’s character becomes the new boss, with all its attributes and powerups — and a new shark must try to defeat it. You can play the game here: www.sharkoboros.com.
