Responsive Rock Paper Scissors app

Hey Soo this is my first proper project after I finished a react course, I don't feel like I am employee material yet, but I'm trying my best to fill in the gaps where I be lacking and make the final push to my first job interview!

I think you could help me greatly with that, all feedback is welcome!

Unfortunately I do not have a specific question to ask, mainly because I'm unsure about pretty much everything.

early thanks!

edit: I did not aim for pixel perfect, just took the main idea
