You have a great app design, but you have not worked on the features that are necessary for the treasure hunt app.
Your application is missing very important features:
-- Allowing the player to select a treasure hunt.
-- Signing up for a selected treasure hunt.
-- Playing the treasure hunt by getting and answering questions.
-- Showing a leaderboard for the current treasure hunt.
We already did this.
We have hiden and disable some elements.
For now i hide some important elements so i can add new one in their place and design without having issues.
Some feedback on your assignment:
