Good implemented project with possible minor architectural improvements.
I hope you enjoyed the process and learned new things during this project.
Furthermore, I wish to see more of your projects in next modules. 🙂

This code looks complicated and contains duplicates.
Could be simplified. See more here.

Too complicated and hard to read / change. Might be simplified by extracting methods. See more here.

Very good approach here. And my suggestion is the same here. It might be simplified by extracting methods and removing duplicates.
