People who play web games in the Itch app show up in stats as downloaders, because the app caches them.
Edit: also, your game is made in JavaScript, which means anyone can see the code anyway, or for that matter "download" the files straight from the browser. There is no real difference online, all files that make up a web page are copied to the visitor's computer by definition.
Okay. It's a bit tricky to get there, but the code and data are uncompressed. They're also too big and weird to be useful, probably.
But that's a silly way to look at it. My games are open source. By all mean, take the code and reuse it. Does it even work in GDevelop? Are you even making the same kind of game?
Most likely people don't need your code. Just worry about making games.
