Interaction with NPCs get boring quite fast. You would need a single 20hrs Story to make it more interesting, but this is far too much work to implement it in a game like this.
Exploration, as it is designed, too. Go here, collect that, fly there collect that as well.
Puzzles/Experiments: All there is are minigames at the moment, and most of it gets boring after the 2nd run.
