Glad the lighting, shaders, and audio landed well for you. If you give it another go, pay close attention to your choices as you push past the halfway mark. Hitting a point where you physically cannot progress isn't a standard difficulty spike, it is hard coded by design based on the narrative paths you pick.
As for the controls, they definitely lean into that twitchy feel which can make things tough if platformers are not your usual style. Appreciate you sticking with it through a couple of runs.
