Hey, sorry for my late reply, but congratulation for your creation!
It makes me think that it would be cool to have an option to test others' particle machine because I would like to see particles travel in this one!
In theory, you can load saves from other people. On my computer they are stored under AppData\LocalLow\Potico\Loopy Particle Simulator. So if someone gives you a save, just drop it in this folder and it should appear in the "load game" menu
Oh okay, thank you!
will share soon.
