Failed us... nah, this is not a failure, you stuck with it for 2 years and I am sure that you learned a lot. Use that new knowledge as I am sure you are doing and make something more. That's just how coding is, you keep going until you break something and figure out how to fix it and avoid it. Keep at it!
P.S. While you may be done with this game I am just getting started. Haven't played much and only just found it on F95, following you here now. Excited to see what comes next.
