Very hard! I struggled to get more than 5 points. It is a good idea though, and I appreciate that you didn't make it as simple as "the pipe flaps instead of the bird."
Some quick tips for you:
-In order to get sharp pixel art, you should change the filtering mode to "point" in the image import settings.
-You don't have to, but it's generally a good idea to delete the _BurstDebugInformation_DoNotShip folder in the windows build files.
