Game Development Process: Crazy Market originally stemmed from a 1982 arcade game called Pengo, released by Sega, which we combined with QQ Tang, a game that was once very popular in China, to create this new title. Given the early release of Pengo, we understood that if we wanted to attract modern gamers, we must have iterations in both art style and mechanics; thus, we opted for a 2D-pixel art style to upgrade the visuals while incorporating some design ideas from QQ Tang. The game received a lot of positive feedback at playtest sessions, and we hope more and more players can experience the joy we once had in our childhoods through this game.
