时之回廊/Corridor of time

The developer explicitly stated in the store description that the studio (铸城工作室) dissolved as of June of the prior year (approximately June 2018, referenced as "去年6月份" — "last June"). After the studio dissolved, the sole remaining developer spent three months completing a final round of updates — adding a new whip weapon, new monsters and bosses, new equipment, and a reworked item stacking system — before converting the game from Early Access to its full release on August 2, 2019. As part of this final update, the online multiplayer mode was removed entirely due to unresolved technical issues and the inability to maintain server costs. The store description explicitly frames all of this as a conclusion: the studio is gone, the developer has returned to solo work, and the changes described are presented as a final accounting to players. The game launched into full release on August 2, 2019 with no post-launch content announcements, no DLC, and no further developer communications visible after that date. The game is complete as shipped.
