I found your newgrounds through your twitter. And I was able to start playing in browser on my iPhone. When the new update is released publicly, will my save files be saved? I use safari as my browser btw.
It should, just be careful about clearing the cache on your browser, as that will erase it! You might be able to keep a backup if you follow the instructions to transfer your savefile from browser: https://imgur.com/a/3vvuB7M
