Cool concept, maybe the AI could be a bit more... tough? Right now it's a bit retarded, so it's hard to judge how fun it would be if the other player is competitive.
Selectable dots should be a bit more highlighted or a completely separate color from the player, as in the late game in a big board where there are a few selectable left, I have to look for clickable dots quite a bit.
One thing I still don't understand is, for example, if the trace reaches a corner where there are 2 possible corners to trace, which one it would choose?
Tbh right now it's a bit bland, maybe add a few more objectives? Like adding stuffs in the middle of the board, and if the trace passes through it, it would have some kind of effect?
