Team Shanghai Alice
After the release of "Mystic Square", ZUN graduated from university and the series became inactive for four years. During this time, he worked at Taito Corporation as a game developer and also composed music for various games created by members of Amusement Makers. He left the group in 2001 to focus on game development for Microsoft Windows, forming the one-man "dōjin" circle Team Shanghai Alice and self-publishing all subsequent titles. According to ZUN, the Windows games represent a "clean slate" for the series canon, albeit with many carry-overs and references from the PC-98 era. Games numbered with decimals are spin-offs from the main series that vary in genre.
