Very cool and atmospheric! The haze and visuals look awesome and really set the mood! I think some control UI in the game could help such as the flashlight and pickup controls, all the information in the start menu was a little overwhelming (but completely understandable with the time frame of the jam). And I think the map could use some more recognizable points of interest, like the buildings silhouette was visible in the haze, but it was harder to navigate and find other points of interest, since they weren't easily visible. The haze/fog looks awesome and you definitely keep it, just maybe making more obvious areas to explore.
Great work! Really liked it! :D
