I've created this thread to support my "Tic-Tac-Tut" turn-based game tutorial. (Asset Store link)
$5 gets you a complete turn-based Tic-Tac-Toe game with 40-page, illustrated PDF documentation. With diagrams!
If you have any support queries, tutorial requests, etc. please post them here. I've set the thread to notify me automatically by email of any new posts.
I do have a day-job, but I'll try to reply to questions and queries within 24 hours. (My job often takes me away from a decent data connection, so I'm not always online.)
