In every game there is an instinctive drive to complete objectives. To reach the end of a stage or to collect an important item. There is always a sort of goal that you naturally want to obtain by engaging with the games rules and mechanics. However, in Mage Kanade's Futanari Dungeon Quest, all you want to do is fail so you can see the explicit scenes, discouraging any true engagement with the actual game. So yes, I would call that bad game design.
