Oldie, but goldie!
Very addictive gameplay, in which u
have to circle squares to gain points. There are 2 different types of levels and a
bonusgame. Its a hybrid of Quix (circle fields of the gamearea) and Pac-Man (enemies
chase u).
Also u have a "bomb" that lets u pass by enemies for a second.

If u manage to circle all corner
squares u become invincible for a short period of time and may munch up the enemies (very much like Pac-Man). If the whole playfield is pasted
u go to the bonus game which gives u some points.
NICE music!
