Although Unity looks hard, I'm telling you that it is so much easier than you think. Brackeys helps with it all, and I think you should try it some day. I'm also pretty young and I think you should DEFINITELY try it (with asset packs if you need it)
I have tried unity and it's just too much coding and confusing stuff
I would waaaaaaaay rather use other engines I think i am going to switch to construct cause it's more advanced than fusion maybe one day i will learn c#
