Stage 28

[Redxll1]

Hi, im actually trying to do the stage 28 but there is something I dont understand, where do I have to go, I tried to climb every hill but every time I fall because of an invisible wall, there seems to be no other way, where do I have to go?

Im asking for your precious help.
Thank.

you have to go to the left and if you are in impossible difficulty take cover by the stairs.

You need to go backwards.
