Which shader to use?

Hi, I want my game to look like this one: https://confusedhamster.itch.io/alchemystory. Is there a shader you would recommend?

 

I assume you mean the in-game screen shots?

I'm sure you could pretty close using the Standard shader. Just set the ambient light (in the lighting settings) pretty high so that the effect of the lighting is subtle. The only thing I'm not sure about is the really fake-looking specular highlights on the pumpkins. Not sure if that's being done by the shader or the texture, though.

Really I'd say this style is 99% due to the textures rather than some magic shader. You'd really need to be able to do some nice hand-painted textures for this to work.
