This game is so cool. I especially love how the hexes bob as you mouse over them. This twist on the classic Minesweeper puzzle (both inverting the strategy and switching to hexes) is really fun and creative. I also love the click sound when selecting hexes!
I don't really have anything useful to suggest for improvements! I think there is perhaps a little too much RNG is clicking around blank hexes for the first half of the game. I don't know if that is something that could be balanced at all by adding more 'wires' or something.
Otherwise, just more levels or level layouts perhaps? Great stuff! Would make for a great mobile game!
