Really sorry to hear this happened! You can go to brave://flags/ and set “Enable Ephemeral Storage” to Disabled and it shouldn’t delete your saves anymore.
I’ve temporarily set up a page here where you can mark levels as solved by pressing M, the save should transfer over: https://steven-miller.itch.io/html5-test?password=save-edit
Thanks! I will try to disable it. And thanks for that page too, although I prefer to solve them again, hard ones like for example glimpse or the wall I already remember the answer, and the ones that I don't I will enjoy to solve them again, shouldn't be that hard the second time! :)
Also it would be amazing to be able to play this game on my phone to think about some map while outside home, you should consider to make a mobile version (preferably on Google Play) if you want or once you think it's ready for it.
