Question URGENT HELP regarding GamePlay

Hi, Im creating a simple 2d game.

imagine(Snake classic).

I have everything ready, Sprites, borders etc. UI is complete. Now I am on to Gameplay.

But iI have no knowledge how to go about.
Do i put the borders into a canvas?
How to scale the sprites according to mobile aspect ratios and resolutions etc.?
What should be the workflow for Gameplay?

This is a simple game. like snake if you touch borders you die.

what should I do now? Kindly guide me in the right direction. I dont have much time as the deadline is near so any help would be highly appreciated guys. Please.

 

not the answer you want but you should start with tutorials. unity has lots of beginner tutorials to get you started but for what your after, there are plenty online for this as well.

i highly recommend going through the unity tutorials as i didn't and wanted to jump straight into making my own game and realized very early that i dont have the knowledge to do so.

 

I've watched i. but nowhere in there is the handling different aspect ratio bit.

What I want to understand is how to develop the gameplay so that it runs smoothly on devices of different aspect ratios.
