Remarkable: Terrific atmosphere created using combination of complete, enclosed environment, audio soundbed, and lighting and particle effects.
Needs Improvement: Lack of feedback (other than in the UI with the numbers going up) when I'm trying to pick up an object (some sort of visual and acoustic indication that items are pickuppable and have been picked up would be welcome. Especially in such an otherwise-polished experience, the lack of this feedback stands out (hopefully you take it as a compliment that this part is "worth criticizing").
Successful: Clever clues and environmental storytelling.
