Project on Hold, Prototype levels done

I have made several playable prototype levels of the game concept. where your plane is about to crash and you have to save the people or goods by dropping them in water.

I did not find the right and fun way to make this concept fun and just need to learn more as a starting (hobby) programmer. Do I decided to leave it at this and start a big Unity course on Udemy https://www.udemy.com/unityrpg . and Continue to this project on a later state with fresh idea's and more programming knowledge.
