About Sizif

Sizif is a 3D endless runner set in a glowing, abstract environment. A sphere rolls forward on its own and speeds up as you move sideways and jump to avoid obstacles.

During a run, you can take risks to collect bonuses. These can make the run easier for a short time, such as by granting a double jump, or double the score you earn. Your score is recorded at the end of each run, and your best score is uploaded automatically.

You can compare scores on two leaderboards: one for your contacts and one global leaderboard.

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.
