Very nice, very good graphics and the best is, it is for Pico 3, 4 too! Maybe sent it to Pico to their Store? The only bad thing ist, the old demo, the button on the wall don't works. What did you use to make it, Unity UE, or Godot?
Yes. Nice you found it. What to do with the Save_OD_FreeRoam.json? I have placed it into the save games dir, was loadable, but did not work: All after the blue bubbles-load screen was black. (Using the standalone-Pico version)
