The application stopped working since I shutdown the back-end on Heroku. I decided not to use Heroku for this project since they don't provide a free-tier anymore and this is a really low-demanding didactic project.

Since the back-end generates the melodies, the application is completely unusable at the moment and will keep showing "Network problem" messages when clicking on the "Impress me" button.

I'm considering to migrate the back-end to one of the following platforms:

• Deta.sh
• Fly.io
• Railway.app
