Yes, the time has come for you to create a small game in Scratch. I know you can do it. I might take a little Grit, I believe in you. You have the freedom to make your game however you would like, but here is what I would like to see:
At least two characters.
Each character should have at least three costumes.
At least two backgrounds.
There should be broadcasting.
There should be a variable or more.
There should be a background sound or otherwise.
You should upload your .sb3 file to your repository and send in your link.
