​

I felt just a standard 3x3 tic-tac-toe project would be boring, so I decided to add two things: larger board sizes (up to 7x7, though theoretically it could be any number if I wanted to implement a custom option) and the option to undo/redo any amount of turns. I feel like I spent way too much time on this (totalling 1 month or more of fairly sustained work) to the detriment of my overall progress, but I am satisfied with the result. It seems to be bug-free for the most part. I do think the code is kind of sloppy, and honestly the HTML/CSS/any JS manipulating the DOM is a bit of a disaster. I was getting sick of this project towards the end, and the visual design portion is definitely my least favorite part.
