About the game
2021 is a small, inventive game with simple controls in which just four keys guide a ball through randomly generated scenes. You must jump thoughtfully and reach the end to finish each level. Meant as a relaxing change of pace from big titles, it was made by 3000Studio.

Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.

The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
