Would nice to have a P vs P option.
Both players must be on. It is not you vs their preset defense team.
You then ‘challenge’ the other player (might need a search function) and if they are around they accept or decline.
If accept you both choose your teams … without seeing who the opponent chooses… so you need a good alrounder?
Board can still look the same but the tiles now go up AND down… so if you leave a diamond on the board it will probably get used by opponent against you… makes for different approaches to fighting.
Will probably need a 5sec move timer or something in case connections are lost or something.
Nice for alliance members to test teams against each other. And just keep things interesting as fighting the game AI can get tedious after a while.
