I think I actually broke the files

So I was working on the game, and for some reason, nothing is working! I cant even see anything! I might have accidentally deleted every single part of the game, but I do have some files that I can try to figure out how to load.

Update: I loaded the game up and it actually worked! I guess I broke the editor and not the actual project.

Update 2: Im dying. I just found out that the reason I couldn't see the level was because I was in 2d mode.
