Thanks a lot for your detailed comments.
They are definitely useful points that I have overlooked.
Music, Sound Effects and Feedback Effects were not included due to time. I understand that it's a week long but due to the indecisiveness on what to build, I only did it 3 days before. Only to be shocked by Unity that I can lose all my codes without knowing what happen 1 day before. But it forced me to learn git for my unity (but those are my problems).
The concept is just to go back to the start when the player dies - "DEATH IS ONLY THE BEGINNING!".
However it seems like I did not provide sufficient features to kill the player or a stage long enough to show this.
Maybe I may have also overthink on the features too. The idea is let the user to know that they should not just drop down if they do not know what is below. There are 'small' clues on how to progress safely for each obstacles.
This is a great first game jam for me as I really learned a lot, forced to complete, did not expect someone to try my game and am super happy someone tried it with constructive comments on how I can improve (Your game is also an inspiration - https://itch.io/jam/gamedevtv-jam-2022/rate/1553825).
Thanks again.
