Your values/strings.xml is not in English

Hey there, I stumbled upon your repo after browsing @ordago's (cloned) repositories. I am opening this issue for a couple of reasons, but I will attempt to fix them while I write this issue.

Leaving your original strings.xml file in German can have a very negative impact on the user experience of your application (see this article about it).

Also, not to bash on @ordago, but some of the translations in strings-en.xml are too generic or should use other words when you read them. I'm guessing he is Spanish since he translated my app to it, so it's not a big deal.

You can see a pull request with my name on it within the next few minutes.

Issues with Build

@CytoDev @ordago could you give me some info on troubles you were having with the build? Would like to fix these to allow easy adaption/customization of the app. I know documentation is very sparse at the moment - would love to improve.

Adding images to challenges

Hi! I am very new to Android development and I was wondering how I could add images to the challenges? So something like "What is the object in the image below?", followed by an image and then followed by 4 multiple choice options. I understand that I would need to add an ImageView but would appreciate some guidance!

Would really appreciate your help!
