Today you are coding in MakeCode Arcade. You will build Galaxy Ghosts at your device: a space shooter with falling ghosts, a speed variable, shots, score, a health bar and damage.

You can already move sprites and run a project. Before you build, think: what might make the ghosts get harder as the game goes on?

You will predict, build step by step, run, and fix as you go. Later you will change one number so the game feels hard but fair.

Galaxy Ghosts has six parts:

1. A player that moves left and right.
2. Ghosts that appear at the top in random places and fall.
3. A speed variable so you can change how fast they fall.
4. Shots that hit them.
5. A score for each hit.
6. A health bar that takes damage and ends the game.

Run it after every part.

Open the MakeCode Arcade website using the link below and create a new project. You can call the project whatever you want.
