At the beginning of the game, the main character doesn’t want to pick up certain items because he feels there’s no need yet—he doesn’t even know what house he’s in. It makes sense that he prefers to first get a sense of the situation. We check all the objects in the house several times. Once we gather enough important information and try to open the exit door, the character realizes he has seen many strange things in the house and decides he must escape. From that moment on, it becomes possible to pick up other items. These are not bugs—the exploration of the house simply unlocks further possibilities.
