Yeah well people not getting keys anymore might be caused by the games simply running out of keys, that doesn't necessarily indicate that the problem is resolved. I'm still gonna wait for some official confirmation that the bundle doesn't grant keys anymore.
The person who found no indication of keys would then have found a steam key claim that simply says "There are no keys available at this time, try again later" when clicking the button, instead of nothing. Additionally, attempting to buy the bundle currently clearly says no steam keys, which it didn't before :
But again, fair concern, you're right to wait, and it's rather unfortunate of itch.io to make the mistake and then not reply to you.
Good luck with this! And with your future games, you make pretty cool stuff =)
