Is this a Glitch/bug or is it normal?

Hello, as you can tell (and where everyone starts) Im a noob… Ive read as much as i can and watched hours of Tutorials (many helped, many didnt)…

Anyway I made a simple game then built it and tried it… It worked perfectly but then I tried to go back into Unity and work on the game it opened the file but there was nothing inside… I tried to load the scene but it was pretty much empty…

So my question is, Once you have built your game, can you edit it. Or does it kind of “Finalise” things, E.g. I cant edit it ever again?..

I would greatly appreciate any and all help you can give…

building a application don’t doing anything with scene. you just should save all your work to scenes and then open it to edit. may be you doesn’t save scene? without scene all your project is just a set of different assets
