天黑请闭眼杀手请睁眼
[tiān hēi qĭng bì yăn shā shŏu qĭng zhēng yăn]
Meaning ‘close your eyes when it gets dark and killer, open your eyes’, this alludes to an online game where killers act secretly during the night phase. Reflects themes found in mafia/role-play games where there are hidden identities and dangers lurking at night.
