Squark

SQUARK is a fast paced arcade game where the objective is to guide your marble through a maze in your quest to capture all the square grids. If you can travel all four sides of a square, then it will be removed from the game board. The devilish green marbles will try to stop you at every turn, so as the levels get higher the action increases. With 30 exciting levels of play, Squark is pure arcade action at its best... a must for the true gamer!

If you capture the yellow outlined square first you gain more points.

It kind of borrows aspects of both Pac-Man and Amidar
