Aqua Ippan (2023 Demo)

"Aqua Ippan is a 2-player co-op platformer game, where players control student divers Itou and Yena, who are being hunted by an armed group after retrieving a lake artifact. The game is inspired by 90s arcade games, with a 'Shoot'em Up' style and Metal Slug-inspired art and animations. Players must use their divers' speed and flexibility to outmaneuver enemies and bring the artifact back to their school."
