yes you can
plug your charger in ur pc and hook it up to ur quest and tranfer file
no, the game would have to be ported, you might be able to export it like that from unity with the oculus tools or something but i dont know, and its not optimized for that, although it is pretty simple. for it to be supported natively on quest dani would have to port it (i dont know anything about that so i dont know how hard it is)
