Carnival is a fun mass event that can be held either privately or with the involvement of city authorities. The Venetian Carnival is widely known, which lasts for several days and at this time the whole city participates in it. At the carnival, masks are a mandatory attribute. Participants should not see other people's faces and this relaxes people to some extent. The heroine of the game Mask Girl Escape received an invitation to a private carnival party, dressed up in a costume and put on a mask, but when she approached the door she found that it was locked. This upset the girl a little, but she knows for sure that there is a key and it is in the room. She asks you to help find him and as quickly as possible in Mask Girl Escape.
