Hi, I was trying to show my brother my save game that I had 25 hours on it and I accidentally saved the game I was in to the 25 hour save. Is there any way to undo this?

Unfortunately not. If your operating system has some kind of time capsule or "revert to previous versions" option, you can use it. You can also see if one of your autosaves is not the 25 hours game. But the game has no way to get back something that has been overwritten.
