Enhanced Attack by Expending Highlight Tiles

At the last meeting we discussed the possibility of an enhanced version of each pickup weapon's attack that can be used by expending a certain number of highlighted tiles:

- When a player claims tiles by walking, the tiles change to the player's color and become also highlighted (we should discuss whether to allow tiles gained from attacks to gain the highlight)

- Highlighted tiles grant the player points over time just like normal colored tiles, but may also be expended to fire enhanced attacks with the currently equipped pickup weapon, and after expenditure will revert to normal colored tiles

- There is no maximum number of highlighted tiles the player may have at one time (we may want them to revert to normal colored tiles if enough time passes after they are gained however)

- The player may re-claim a currently owned colored or highlighted tile to highlight it, and this replaces any old highlight with a new one

- When a player fires a pickup weapon, if the player has more than a certain number of highlight tiles, that quantity of them is expended, and revert back to normal colored tiles (reverting in order of oldest to newest acquired)

- When highlight tiles are expended to fire a pickup weapon weapon, an enhanced version of that weapon's attack is fired (we may also want the improved attack to not expend the weapon's single use ammo, and allow consecutive shots as long as highlight tiles are available) (we may want to implement a cooldown between improved attacks to avoid a player gaining too much advantage from attacks with disabling effects)

- It will be difficult to build up a large number of highlighted tiles because other players can claim those tiles by walking or with attacks

- If a player's highlighted tile is claimed by an enemy player, all the player's remaining highlighted tiles gained prior to the one just lost will lose their highlight status and revert to normal colored status

- Highlighted tiles or the player should show some visible display that there are enough highlighted tiles to fire an enhanced attack

- Highlighted tiles should show some visible display that they are being expended for an enhanced attack rather than simply being lost without purpose

- It should require sufficient time and effort to gain enough highlight tiles for the enhanced attack that they cannot be fired frequently, and gaining enough for two enhanced attacks should be nearly impossible unless opponents are totally ignoring the player
