Modify an existing multiplayer game in JS

Job ID: 32635738

Budget: $750 – $1,500 USD

Hello,
I would like to modify an existing multiplayer game.
Here is the code of the game: https://github.com/yandeu/phaser3-multiplayer-with-physics#readme
You can see the game live here: http://phaser3-multiplayer-example.herokuapp.com/
I would like to give the player the possibility to collect stars like in this project: https://phaser.io/examples/v3/view/games/firstgame/part10
The server has to be authoritative and the client/server must use interpolation and reconciliation
Thank you for your interest
