Sorry about all the questions, but are we aloud to use Construct 3 to make our game, or no because it has visual code?
Yes, you can use engine that you want.
"You may use any engine (godot, unity, ect.) as long as it is playable on Windows. Ideally, a web build or html build for browser play so that MAC users and others can easily play off the itch.io page itself without downloading. I understand that we all don't have the specs to do an html build, so I will not hold it against those who cannot do so."
