I think it was just that at the time (or for that magazine), 80% was considered a very good score. They are mostly positive, and praise the non-distracting visual style.
I do agree that on ‘easy’ the game provides virtually no challenge, but hey – that’s what the harder difficulty levels are for, no?
I remember Cool Spot, which they compare it to, being much more annoying to play, and not in a good way.
