Hahahah
Yeah I've noticed that the negative reviews have received a 'useless' vote but the positive ones have received 'helpful' despite how short and utterly useless they actually are. Your judging on review as to whether they are helpful or useless should not be based on whether they are positive or negative, but instead on if they are actually valid and fair enough reviews.
And I must say that the "negative" reviews are fair enough because the art is awful, the gameplay is very boring, takes no skill whatsoever, and has no atmosphere except dullness.
