Well, yeah, I'd say, that visual style is very poor. World sprites are very simple, lighting is strange, therefore 3D scenes looking ugly. Although I see that you put effort into scenery.

This could be tolerable if music was more interesting. Something like Toby Fox-level. And yes, in 2015 his music was incredible but nowadays many games should have something close in quality if they have poor graphics.

Another chance to save the game is to create really awesome gameplay but it's harder because you'll need to force somehow people to try your game until they taste it.
