I have zero experience with UE but I think you can animate there too. It's a powerful engine after all. Good luck with your project!
Thank you, you know, it would help to have an experienced game creator, you don't have to, but if you do, you won't need to do that much, you can do as much as you want, at most help create everything or as little as just creating the models, again, you don't have to because of your game demo turning into a full game and you being a one man team, so please do what you like, not what I want you to do. I'm 14, so I can't pay you anything, so do what you want.
