Abyss is an arcade game on Aqua Venatus in which you click on the boxes that are grouped together in order to remove them. You can see many colorful boxes in the black background. Like the green, yellow, red, or purple boxes, and it is beautiful. Click on boxes you will earn more points for finding larger groups. Points are doubled in bonus rounds. About the bonus meter, when you removing boxes will cause the bonus meter to increase. Once the meter is full, you will be able to play a bonus round after the current round is over. On the motion meter, the next column of boxes will move forward when the motion meter is full. At last is the life meter. Bars will be removed from the life meter if any boxes fall off the platform. So you should wipe out as many boxes as possible.
