Unity for text app

Hello community,
I would like to ask few questions about using unity for app including only text. I want to make a game in quiz style therefore I will mainly use just text and images.

First question is how can i reduce the app size as much as possible ? Which image type and resolution should I use (it will be android game) ? Has anyone some experience with working with text only, how to reduce the size and other tips connected with this topic.

Secondly is there any asset that would be helpful for me ? Nothing expensive please.

Should I create text as a script or as a UI ?
And is there a way how can I write a mathematical symbols such as squared etc in Unity?

Lastly, should every new “question” be in 1) separated project or 2)separated canvas or 3)written in separated images ? What would be the lowest size and the best solution?
Thank you very much.

Creating a quiz-like game in Unity is no big deal.
If you are working with text and images only, you can reduze the size of your project by not using high resolutioned images.


Should I create text as a script or as a UI

It depends if your text will change during runtime.
If your game will have a header with “Question”, you can just write this down in a text element.

However, if your game will hold e.g. 4 answers that will change for every new question, you should create 4 text elements and write a function that will change them to your desire.

To answer your last question: as said before if only your answers and questions will change just use one scene with one canvas and change the element.
