I was creating new designs in unity and while creating a new level I created a mess but, I have saved changes in source tree version control. I want to revert back to that previous commit, can someone please help me out, I would really appreciate it. Thank you.

Welcome to our community! 
I think the lecture named “Back-pedalling With Version Control” (currently #109) could be helpful. Have you already watched it?
