About Sufficiency

Sufficiency is a room escape game set in a strange space. You have lost your memory and do not know your purpose. Find a way out by working out how to use each item and facility, with few textual clues to guide you.

Solve the puzzles

You solve the puzzles based on your own understanding of the items and facilities. The game has an original puzzle system, art style and music, all created by Yiico.

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.
