Settings in settings menu:
- meta level: ranges from 1 (normal tic-tac-toe) to 4 (81x81, four levels of nested boards)
- AI difficulty: how long in seconds will the AI think about the move. 0 is random moves, 3 never loses normal tic-tac-toe.
- game modes: singleplayer, multiplayer, automatic (AI vs AI) or randomly fill board.
Rules
Each board contains 9 a smaller boards. The lowest meta boards are just normal tic-tac-toe boards where you can place your signs. Where you move in the lowest board controls on which higher board your oponent can make their next move (indicated by the colored squares). Winning a lower board replaces it with a sign in a higher board. Win the highest board to win the game.
If you didn't understand that's my fault, I suck at explanations. Try it for yourself at small meta levels, it's not as complicated as it seems.

@merwok I am planning on adding a CPU player, but I'd like it to be reasonably challenging so I'll be trying to implement alpha-beta pruning, which may proove difficult in PICO-8.
I don't see anything wrong with the squares. The idea of meta tic-tac-toe is that each move restricts future moves, so the next move indicators should move with the current player's cursor.
The smallest square inside bigger squares of the same color shows where the current player is planning to place a mark. According to the rules it will restrict next player's move to a certain board, which is shown by a square of the other color. It is intended behavior and it reflects the (poorly explained xd) rules of the game. Having your move influence your opponent's moves leads to more strategy than just freely placing marks everywhere.
I think Pico Checkmate uses alpha-beta pruning if it would help you to look at somebody else's implementation?
@merwok blue move will restrict green move to a certain board which is represented by the moving green square. This is intended and helps to understand rules of meta tic-tac-toe. You not only choose where you place your mark. At the same time you choose where your opponent can place their mark, which is reflected by the green square.
