Sent you an email. Sorry for all the trouble. Thank you for being so patient!
I sent a support request to itch.io but they haven't replied yet. If I don't get an answer this week I can send you a key.
As far as I can tell everything is setup right. You might need to reload the purchase page. There should be a button. If it's still not working let me know.
I'll look around, maybe I missed something. I'll let you know if I find something!
I hadn't thought about it. The steam keys should be available now
Would be nice to be able to keep the button down to move up instead of clicking like crazy. Being able to use the space bar might be nice too. Congrats on your first game!
