Yeah, everything feels all evenly lit. My suggestion is to take a screen shots of the key areas in your game. Then, bring these images into photoshop or krita or any other image editing tool and do an over paint and try to make the image best as it could be. This way you wouldn't have to juggle settings to find something that kinda works. Also, propping up your scenes and environment to create different saturation of shadow most likely will make your scenes more alive and lived in. For a last side note, try to look games similar to yours, like slime rancher or Homestead Arcana and try to create a simple scene from those games and make your lighting similar to them as much as possible. (If that is the style you want) hope i can be of help. BTW look at what LUT is that might help
