you have to click on the eye in the top left corner, then you'll see a text field popup. In there you type the object name (the name you'll see after you clicked on the bed for example. and if it was the Fake object you will hear a correct sound, if not a incorrect sound. Stage 1 has 5 objects. And my honest opinion: its really hard to make out whats the fake object and whats not. GL HF
