Hi, I have just updated the game with highscores and some other achievements.
This game is very hard that the thread can only be started from the border. Release your key you can make you spider retreated. I 'm sorry about getting stuck, it maybe a skill for you to get some areas remained by the side of pebbles . When spider move between borders, only smaller half get filled.
