Slay the Spire 2 faced review bombing from players in China over reworked Act 3 boss Doormaker. The changes first appeared in a March beta patch and moved to the main branch in April. A recent video explains the concerns tied to save loading playstyles.
Mega Crit released Beta Patch v0.100.0 in late March, which reworked the Doormaker boss. Chinese players responded with negative reviews on Steam, citing balance issues with the fight. The same group protested again on April 17 after the major update carried the changes to the main branch.
