Ok first, the nightvision is not quite efficient, unless you press N rightafter pressing Tab (before the camera's on), and the you got a pretty great nightvision haha!
I think the atmosphere lacks a bit of build up through the audio. To me the environment and level are well designed but the jumpscares come in so abrutly that I was not so frightened.
Did you have something planned with the camera other than the nightvision? If not, then why not just use a flashlight? It would have been implemented way faster and so you could have spent more time on the spook. I feel like often we don't wanna give up on ideas during jams even if we don't have a good use of it, just because we like them ^^'
Overall nice game. I liked the art and level design.
