Just a heads-up: I don't know what source this game or key is from, but recently, quite a few of the keys for this game got revoked by the devs, and the process of getting a replacement may be a bit complicated, potentially unsuccessful. See https://steamcommunity.com/games/Typical_nightmare/announcements/detail/1721964871624914889 if it comes to that.

(I won a revoked key for this one and had to mark it as "not received", because the giveaway creator stopped responding.)
