My robot-themed Tic Tac Toe game is ready for feedback!

I’ve finished my tic tac toe project.

Play it here

Some things to note:
The DieNet(hard) mode opponent doesn’t quite use a minimax algorithm so it’s not as aggressive as, say, Google’s AI but it should still be pretty annoying to play against.

The RESET button that comes up after the end of the game is disabled in CodePen outside of debug mode but what it essentially does is reload the page, so if you would like to RESET please refresh the page instead as it does the same thing.

The first player alternates each game regardless of who won but keeps their respective symbol. X goes first, O goes first, X goes first, O goes, first so on.

The opponents may or may not be inspired by other robots in fictional media.

Any feedback is appreciated! :V
