Ah, nostalgia.
I haven't played this game since I was in the second grade, on one of those really old 5 1/4 floppy drive macs. The game itself is pretty good. The number muncher should open his mouth when he's over a number to make it easier to see. Also, the controls are -way- too sensitive. I have to lightly tap the arrow keys or else i'll go over two or three squares at once. Otherwise, good job.
