It apparently corrupted your savefile. I don't know how to delete files in the browser... Maybe you could switch to the Steam version?
Unfortunately I don't use Steam,
I managed to start the game in 0.2.0c patch file, but its very laggy on my desktop.
Try clearing cookies?
I'm playing the game on Itchio app, not sure if there's a way to clear cookies.
Clear the app's cache, depends on your OS but you can usually do this by hold pressing on the app icon until a menu appears.
I followed your instructions and cleared the app's cache and cookies, but it doesn't work.
Maybe it has something to do with the game files? I still can't access the game even after reinstall the game.
