Making a quiz based game in Unity 2D

Hi all. I am trying to make a quiz based game in Unity 2D where questions fall from top to bottom and we have to answer them before they hit the bottom of the screen by selecting 1 of the 4 randomly generated answers out of which 1 is correct

How to proceed with the game and what tools in Unity to use. Also is Unity good for making such a game or should I make it directly in native Android

First of all you need to learn the basics of unity 2D.

Unity is surely best for most of the games like this. It is easy to use but you may use something else if you are not finding unity suitable for your work.
