Looking for some feedback on this app I have just designed

For my portfolio, I designed and created an imaginary app (based around mystery locations) for my portfolio.

Could I please get some feedback and critiques on the whole overall concept as well as my designs. The portfolio will take you through what the app will be about.

The app

Thanks!

Great design resource
