How to Reverse Engineer a Unity Game | Kodeco, the new raywenderlich.com

Hi, Thank for the tutorial!
Can you explain what to do it the “Assembly-CSharp.dll” is very small and does not contain all the methods?
I am trying to RE a new version of a specific app.
While the previous version had a complete and full “Assembly-CSharp.dll” with all methods/classes the new version “Assembly-CSharp.dll” is much smaller 53k(new) VS 2.1MB(old).
How do you suggest I proceed?
Thanks
I’ll be happy to supply more data if you want.
