I could only get over the first wall jump so I'm sorry I couldn't get to the rest of the game. I like the vibe and the music is really nice. Sorry I can't really say much more

There is no wall jump there.
To get through the section with walls, you need to use a weapon that shoots spikes that stick into the wall. To get this weapon, you first need to obtain the first part of the chyrograph (in the church using a grenade launcher) and then defeat the boss again. Unfortunately, I didn't have time to explain this section of the game in more detail.
