Sorry to hear those didn't work. Could you try grabbing the game from our Patreon and trying that? Sometimes the servers on Itch are wonky and cause some issues after downloading.
This is the latest free version. It requires a Patreon account, but free to create an account if you don't have one already.
Give that a try (saves should sync over automatically). You could also try the compressed version of the game, which lowers the image/quality a bit, but lowers the download size too.
