Jono

Jono is a tiny platformer hero with a very long road ahead: one million levels, and only one Jono in the whole world. When your turn comes you get one minute of control, then the next person in the queue picks up exactly where you stopped. Everyone else watches the run live, cheers or heckles in the chat, and leaves emotes.

Nothing is lost. A death only resets the current room, every room anyone clears stays cleared for everyone, and each death leaves a gravestone so the next player knows where not to jump. Rooms mix stairs, spikes, crushers, ice, portals, dark rooms and chasing spike walls.

Part Time Monkey launched Jono on 4 October 2026. Seventeen days later the developer reported 4,800 hours played, with six players past 100 hours and one who had cleared more than 7,500 levels on their own. Reddit called it "massively singleplayer". The game is free on Steam for Windows.
