I'm learning a language, and want to make a game of it

I’m learning unreal engine, and for my own fun and challenge I wanted to make a game that involved activities that have given me the most success in the past, I don’t know that I want a 3d game, though I haven’t decided yet. I want to practice dictation, and listening skills and I was wondering which game mode on UE would be most appropriate for that? I think I saw that there was a 2d puzzle option? It’s going to be specifically doing things that I have trouble with, and I don’t know that I’d ever publish it.
