I followed the Block Breaker tutorial all the way through and it is playable. I wanted to change it a lot but first I needed the dimensions to be 1920x1080p (HD) but I cannot figure out how to do that. I changed the reference resolution in the Game Canvas and changed the display in the Game Tab to 1920x1080p but the mouse cursor continuously get un-aligned with the paddle (It actually does work with the 4:3 aspect ratio and 1440x1080 reference resolution which the course told me to do) so please help me with this soon because I want to work on it more.
EDIT: I also want to release my changed version on Google Play and it does the same thing for any other resolution. I even tested it in Device Simulator as well.
