Peer to Peer code Review

[Alexander Santiago Cárdenas]

It's a really good project. We think there are just a few things you can do to improve it.

• We think is a good idea to constrain the score input just to accept numbers.
• Kindly reduce the music volume It could be annoying if it is louder.
• Kindly fix the mute button when you click on it for the first time It doesn't work.
