I played it on chrome on my phone.
It's somewhat playable on mobile using your web browser though the lack of the right is not the best.
You have to hand it before given the potion and only if you're gonna give them a ditzy potion.
Even with the downloaded version it opens a tab on my browser and I'm able to load my saves on starting screen.
When you start the game there's a load hyperlink.
At the start of a new day there's a save game and it make .json file.
