CoAnnCo

CoAnnCo is a cooperative puzzle platformer built around four players working together. Its obstacles are designed so that they cannot be solved alone: players step on one another, time their jumps together and combine their efforts to move heavy objects. The positions and movements of all four characters form the solution to each puzzle, and if the group separates, the stage is restarted.

The game features 15 stages, each introducing new rules and mechanics beyond basic running and jumping. The characters are rice balls with physics-based interactions, so players can accidentally push or drop one another off ledges. Controls are described as intuitive, while the puzzles themselves demand a high level of coordination between participants.

Two modes are included. Story Mode saves progress after each cleared stage, allowing players to replay earlier stages and continue at their own pace. Speedrun Mode displays a timer at the top of the screen and challenges the group to clear every stage as quickly as possible; progress is not saved during a run, and a record is only registered once all stages have been completed.
