A beginner with too much ideas needs your help

Yeah, I’ve done some projects with C++ (Tetris, music player, match 3 game), a lot of java (2D network game with some A* AI, file management program, library manager used for school library, match 3 game, some picture transformation like automatically changing a color).
Also a little bit of C (Sokoban-like game).

Nothing really fancy as I focused on programming not on graphics.

I’m planning to mix blueprints and C++ for my UE4 projects, at least at first. I don’t want to make only blueprints projects.

I’m feeling comfortable with logic. I’m not a pro yet, but I am not a newbie neither.
