How do I add correct behavior to enemy with right Animation

I am trying to add patrolling behavior to sprite in platformer game. When following to tutorial i get my sprite upside down with wrong animation.I have tried using overlapping logic and collision with 2nd object but aniamtion is always wrong. HELP me in doing it right. i have attach my project file

You are rotating your monster instead of setting it mirrored..

Also the collision polygons of your wall object aren't very good, so your monster gets stuck a lot..

I have used multiple blocks to create a wall but since i have used snap to grid i thought all collision box will not create a problem. and i tried flipping and mirroring but that don't change the problem. can you show to do it correctly

Here:

Thanks man i got stuck on this for whole day . At last Now i can add new features. Thank you.
