I really like the idea of this game, I do wish it was possible to capture large amounts of area by surrounding tiles, I do think a level of polish could've made this game super satisfying, like maybe some visual reward for taking an opponent's piece. The music was simple, but it worked, and the game didn't have any bugs I ran into for the some 10 minutes I played.  the AI is also pretty impressive it didn't seem like it was just random either.

Takes a bit of time to understand, after laying lots of tiles.
Nice little game.  

cool GO approach, it feels a bit flat until you understand how to switch enemy colored tiles. also it'd be awesome to conquer tiles that are fully surrounded by your paint

or having blocked- unusable tiles

interesting idea!
