Android App - Halloween Countdown

Halloween is approaching. I have developed an android application for you.
Halloween is approaching here. Please install the application and leave a beautiful star. Come on practice!
Can you tell me the steps I need to improve?
I am waiting for your comments.


Hey the app is great, left a review as “Puzzle World” can you please rate my app:

Slope unblocked is a pleasant and engaging game that can be played at any school or high school in the United States.
