How to update my game?

Depends on the platform. You will have to check how they do it. But yes, generally, you just upload your whole newest build. Steam/Itch.io does it this way.

No problem. Please mark the answer correct so this can get closed. Thanks.

I want to sell my game eventually, but I wanted to know how I update my game. Do I just reupload the game with its new changes, or do I just reupload my new/changes files? I wanted to know early incase there was something I should do ahead of time and/or during development.

Thanks a ton. I have made games before, but this one that I am making is my first full length game so I am kind of a moderate beginner(if that makes any sense), so things like these are a huge help.

One thing I ran into, how do I update while still keeping the player’s save data?
