This was one of the most original concepts I saw in the jam. I really liked the idea, and I think it was executed very well.
At first, I didn’t realize I had to keep interacting for longer to get classmates to give me the exam answers. A small visual indicator, such as a progress bar or a circle gradually filling up, would make that much clearer while keeping the clean UI you’ve designed.
After a few attempts, I managed to finish the game. I assume waking up in the bedroom is the good ending, since I believe I answered all three exam questions correctly.
My only real suggestion would be to slightly lower the movement sensitivity and make the interaction hitboxes a bit larger. The combination of those two things made some actions harder than they needed to be. We actually ran into a similar issue in our own game with the coins and the slot where they had to be inserted.
Other than that, I still think this is one of the most original entries in the jam.
Great job!
