Some things you should know as a new game developer:
Do NOT use the built-in text pipeline. Use TextMeshPro, Which can be accesed by right-clicking in the inspector and adding a "Text (TMP)" object.
The blurry images when importing pixelart can be fixed by going into the import settings for the sprite and turning the filter (by default it is "Bilinear") to "Point" and setting Compression to "None".
I wish you luck on your gamedev journey!
