Nice game, it took a bit for me to really get the hang of wallrunning and grappling but I figured it out, I kind of cheesed the boss by just running constantly to the side and spamming my gun (unless that is how it is meant to be fought), I was able to easily abuse wallrunning to scale vertical surfaces so maybe just make so that way if you jump off you get pushed away from the wall, overall though pretty decent game.
