Need some help

Hello, I’m in my last year of high school and i need to do a project for my graduation and since I’m studying programming i thought of doing a game, i never used Unreal Engine/Unity but i have experience in Visual Basic and C++, how diferent is it compared to UE4? I was thinking of doing a Zelda like 2D RPG but i can only seem to start 3D projects, is there a way to do a top down 2D game with UE4? Thank you in advance and sorry for my poor grammar.
