About The Janus Problem

The Janus Problem is a single-player, first-person puzzle game set in a virtual testing environment. You use time manipulation to solve each room and reach its exit.

Manipulate time

You create time marks that return objects to their positions at the marked time when recalled. You can also place time locks on objects to prevent them from reversing. By combining these tools, you coordinate object movements to solve each level.

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.
