It's probably something with your browser cookies, are you using something like incognito mode where they're not saved?
(And do you really need the saves?! It's not a particularly long game...)
I'm working on new update that should better support fullscreen, etc. so be ready for that
No, I haven't been using incognito and I haven't been like resetting my browser history or anything either.
I just wanted to kinda play the game at a slower pace, and only make a little bit of progress each week. I didn't want to experience it all in one sitting.
But I am looking forwards to the next update then! Thanks for sharing that.
