Thanks for sharing the feedback and giving it a second look!
I'll also add, that this is one of my biggest weaknesses as a dev in providing error message in the UX in the exact manner. The code traps for them, but doing anything more than letting the dev know is where I stop as well. Maybe that's why I was keen to go looking for it, as I just finished updating one of my projects in this exact manner. I probably spent just as much time in error handling as I did in writing the code. Others will probably all nod and say "yup". ;-)
FYI, I did try your game in a non-locked down version of my browser, and really enjoyed the creativity of slogging up some SQL. I'm no DBA, and I did learn a few things that I don't typically deal with in my limited usage, so thumbs up all around!
That is brilliant news that you gave it a try and enjoyed it, even better that you learned something! Thanks again for the time you took to feedback, and the time to follow up!
