Free Steam Game Jono Lets Only One Player Play at a Time for Just 60 Seconds

A free indie platformer called Jono is attracting attention on Steam with an unusual multiplayer concept: only one person in the world can control the game at a time. When others are waiting, each player gets a 60-second turn before handing control to the next person in a global queue, with everyone working toward completing one million levels.

Developed and published by Part Time Monkey, Jono launched on Steam on October 4, 2026. Instead of traditional multiplayer, the game uses a single shared character whose progress carries over between players. Everyone waiting for their turn can watch the action live, chat with other spectators and contribute to the same ongoing adventure.

At its core, Jono is a simple 2D precision platformer where players guide a small character through increasingly challenging rooms filled with obstacles. However, the game replaces individual campaigns with a single shared experience.

Players join a global queue and wait until their turn arrives. When others are waiting, the active player has one minute to clear as many rooms as possible before passing control to the next person. If nobody else is in the queue, the timer does not run until another player joins.

Once the turn ends, control passes to the next player, who continues from the exact point where the previous person stopped. Everyone else watches the active player in real time. Spectators can participate in a global chat, send emotes and react to successful jumps or costly mistakes.

The developer describes the unusual format as "Massively Singleplayer," reflecting how thousands of potential participants share one playable character rather than exploring separate worlds. There is also an additional restriction when the queue becomes crowded. If at least five people are waiting, the active player has five lives alongside the time limit. Clearing a room restores those lives, but losing them all ends the turn early.

This creates a different type of multiplayer experience, where cooperation happens through taking turns rather than controlling characters simultaneously.

The long-term objective is to guide Jono through one million unique levels, with every completed room permanently added to the community's progress. Unlike conventional platformers, dying does not erase previous achievements. A failed attempt simply restarts the current room, while every earlier stage remains completed for everyone.

Deaths also leave gravestones, showing future players where previous attempts went wrong. The rooms introduce different challenges, including spikes, moving crushers, ice, portals and environmental puzzles. Some levels feature pursuing walls of spikes or mechanics that change the orientation of the world.

Most stages are procedurally generated using predefined patterns, but the game also supports player-created levels. Through the built-in editor, players can design their own challenges and submit them for inclusion in the shared journey. They must first demonstrate that their creation can be completed.

Approved levels are added to the global progression, meaning other players will eventually encounter them during their turns. For particularly difficult creations, the game offers a separate mode called Meat Grinder. This allows players to tackle extreme user-made challenges without blocking progress through the main journey.

The unusual format has quickly developed a small but dedicated community. In an October 22 post, Part Time Monkey revealed that players had collectively spent more than 4,800 hours with Jono open during its first 17 days.

More than 100 players had kept the game running for over 10 hours, while six had exceeded 100 hours. One participant had personally completed more than 7,500 levels. The game's social features have also attracted considerable activity. According to the developer, players had sent more than 85,000 chat messages, with over 540 people participating in conversations.

This suggests that watching others attempt difficult levels has become an important part of the experience, rather than merely something players do while waiting. The developer estimates that the community has been clearing approximately 5,000 levels per day, although the pace could change as more challenging rooms appear.

Players can also earn cosmetic rewards, including hats, visual effects and trails, while daily and weekly leaderboards track individual contributions.

Jono is available now as a free-to-play game on Steam for Windows PC. The developer has not revealed what will happen when the community finally completes its millionth level.
