Since we moved in the last year, most of my Vectrex games are in a box waiting until I have time to set up a new game room, so Minestorm was the only thing we played for 'Vectrex-day' this year. 7-year-old was really into it. Actually she wanted to play the next night too and we put Bezerk in after a few exciting rounds of Minestorm.

7-year-old managed over 11000 and over 13500 the next night:
