Thanks for your comment!
I noticed that quite a few people mentioned the astronaut dragging mechanic. It's actually intentional—you need to drag the astronaut as if you're grabbing them, then release, grab them again, and keep repeating. That's part of the challenge. Also, the faster and harder you drag, the speed the astronaut gains.
As for the exam, each question is meant to take about a minute of thinking on its own, yet you only have one minute to answer all six questions. The idea is to make you feel the pressure of the countdown rather than give you enough time to solve everything comfortably.
The game doesn't force you to retry, either. The story end whether you pass or fail the exam.
