First game develompent

Hello everyone, I’m a complete beginner in JavaScript and game development, and I want to get started but don’t know where to begin. I’ve drawn a rough layout of the main screen: the ship should shoot lasers at coins, increasing the score in the game. Could you please suggest where to start?

Hello. Start from the official Making your first Phaser 3 game tutorial to study basics things. I have replaced Arcade Physics with Box2D-WASM
