Extended the deadline a couple days for anyone having upload problems.
If you're seeing this after the extended deadline and you need a late submission key, tweet me at sakevisual.
That could be an issue with how your browser handles itch.io's code. Try using a different browser to download it if you can. If that doesn't work, we also have a mirror of this file on ModDB: http://www.moddb.com/games/re-alistair/downloads/re-alistair
The file shouldn't be protected. It's automatically generated by Ren'py and doesn't have any password protection. I've added a second upload (Windows only - let me know if you need the Mac version instead). Hopefully that will work.
