Okay, so general cookie testing:
According to https://arty.name/localstorage.html
My browser can save over 5 million characters.
And yes, I can accept cookies in order to log into websites; such as having an itch.io account.
According to http://www.sharonminsuk.com/code/storage-test.html
I can load HTML5 session information just fine.
Further reading:
I see that the issue extends to many other games on itch.io
Looking into this further, the hwcdn.net server that itch runs will serve cookies in a 3rd-party way.

Cookie-jacking is a real thing. That's why these settings are the way they are. But perhaps if I tweaked my browser settings, I could access the game?
I change my Chrome browser settings for the itch.io website:
Sites that can always use cookies
v6p9d9t4.ssl.hwcdn.net
Including third-party cookies on this site
itch.io
Including third-party cookies on this site
I shift+refresh the game's web page and try again, but alas - no. No change.
Would you know somewhere else (a web server or something) that my browser would load the cookies of your game from?
Thank you for replying!
