---To do---
1. To Change the suri gabs between each others ; When merged, it's inevitable lol.
2. To fix merging burg ; even if the player is not captured by an enemy set as 'isSpider', if player shot the enemy, "merging" is occurred.
-Done-
Added Capturing player animation.
Added Viming animation.
Added GobackSpider animation after capturing Player.
Edited the rage of criteria X : from spider.x+-10 to spider.x+-20, when A spider is viming.
Disabled press key when Capturing player.
Changed setEndGame not to end when merged player got shot; merged player will be single player after explosion.
Changed that when ONLY 'isCaptured = true' and when isSpider is exploded, Player is merged as 2 galaga.

-To do-
To Change the suri gabs between each others ; When merged, it's inevitable.

To Limit move area, playing with keyboard (galaga will go unlimitedly; over screen).
