On windows they're stored at:
C:\Users\[USER]\AppData\LocalLow\Ekull\Greenhouse
If you're not using windows I'd have to look into it..
I privated it but you can still access it here: https://ekull.itch.io/wheel-of-kinks code kink
That's.. Really weird.
You could try going into preferences, clearing save data and trying again. You could also try going into the load menu, selecting a blank file and clicking load, this is an alternate way of creating a new game.
If none of that works I can only assume you android device isn't compatible with my game saving plugin, but even that doesn't make sense.
