Deliver Us from Serpents is an excellent submission and one of the strongest uses of the jam theme I have played. The idea that the people you rescue may not be human is already unsettling, but making the maze alter your chalk markings means you cannot even fully trust your own route. That is such a clever and memorable interpretation of "Trust No One."
The atmosphere is fantastic. The pixelated visual style, lighting, props, environmental variation, and filter all blend together really well. I also loved the handwritten opening narration with its sound and animation; it is a simple presentation choice that sets the tone perfectly. The altar, prayer, chalk, holy water, and fragment systems give the exploration a great ritualistic feeling.
The only small suggestion I have is to show a brief in-game reminder while the chalk is equipped. I initially had to return to the controls screen to understand how to change the chalk symbol and direction. A compact tip in the lower-left corner would make that mechanic easier to learn without taking away from the mystery.
Overall, this is a very well-made, intuitive, and genuinely intriguing horror maze game. Congratulations on a fantastic jam submission!
