Help me with resolution building 2d game

Hello guys. I need a help. I made a game with free aspect ratio (9:16), but when i building it, its has another resolution. link on game https://www.sharemygame.com/share/50eab7e3-8348-4832-a53b-da9a69cd8676

 

use a canvas scaler object for resolution management

 

still not working

 

set UI scale mode to scale with pixel size, mess with its other settings until it works how you want.

you may also need to set your camera to screen space.
