the art looks amazing! the noise shader is very interesting, though it's kinda weird that it doesn't affect the player even a little bit
i wouldn't recommend you start off with a wall of text though, maybe split it up into multiple dialogue bits. i've got a few nitpicks about the wall though: 1. possessive it is its, not it's, 2. you get 1 bit of colour information, not 2
it'd be nice if the camera didn't keep the player strictly centered, it could look ahead by a bit to make it feel more lively
it's weird that when you stand on the charge cell thingies you get charged constantly even at full charge
maybe add a warning when you press R to teleport to the start
the shadows let you see a little bit through closed doors which is kinda weird
a bit strange that you keep your items when you die, wouldn't you lose them?
you can also just camp outside the turrets' range to hit attack them, it would make more sense if they locked onto you once you hit them if they have line of sight
it would also be nice if the map was less linear, though i can see how that's out of scope for a jam game
i liked it a lot! the story is pretty intriguing and it looks amazing
