I took a week off work to do this and put all my free time into it. It still ended up taking the first 7.5 days to get those working (and still slightly buggy). That's part of why I'm so light on actual game content. Sorry!
I will give itch credit for carrying part of the heavy load. I use their authentication to verify users, so I don't have to do all the account creation work.
I hope you enjoyed playing!
