Here is a fun game called Qiller. It is similar to the classic game Qix.
The goal is to fill in 75% of the screen to advance to the next level.
Instead of drawing lines and making boxes to fill, like Qix, you click on a spot with your mouse in Qiller and it makes an expanding circle.
Avoid baddies and pick up bonuses.
Any hints, tips, and tricks are appreciated.
My Current High Score: 23.6M
One tip is to click rapid-fire to draw a line. Use the line you drew to box baddies in the corners, up against the wall, or wherever.
