Your main goal is to choose correctly and enter one of four doors. Secret locations and hidden places are important to understanding the plot, and objects and details in your surroundings can serve as keys.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
