Earth ReGen is a free desktop browser game about reconnecting machines to revive a ruined planet. It blends automation, puzzle and casual play, requires no account, and offers a demo covering the first two areas.
Players start out clearing a rubbish tip by hand, after which machines take over the work. A machine has separate sockets for workers, electricity and materials, and stays inactive until wires join them. Refuse is turned into metal, refined into aluminium and steel, made into batteries, and finally converted into a continuous power supply. The free demo holds the first two locations, about ninety minutes of play, and ends with a conclusion. It runs only on desktop browsers at present, with a Steam launch planned later. A recent update introduced three machines earned by completing Trials, and reworked wiring: keeping Shift held lets you place wire after wire, dragging bends a wire, and reroute dots gather several lines at one spot. Land that recovers fills with butterflies, fireflies and bees.

I made this game with the new Gemini TTS, it generates the voices from a description and has really warm inflection
