“BOH is an original, retro-flavoured game of exploration and action.
You move in claustrophobic, traps-packed, mind-boggling battlefields searching for the Evil Masters, who throw countless enemies at you until you discover and face them in the final battle. Although your quests are made slightly less hard by the bonuses and power-ups scattered all around, carrying out the missions demands lots of concentration and quick reflexes. ”
