The art direction is very cohesive and I liked the inclusion of lighting and shadows which made the entire world feel responsive and dynamic. Like others, I couldn't really figure out a lot of the controls - the resource numbers at the top left were intuitive to me, but the buttons at the bottom left didn't look interactable, and mining also never worked for me. But I think with a little bit of polish, and also adding some other mechanics so that gathering resources is a more varied experience, it is a really good game to build off of and turn into a bigger tower defense game if you ever want to.
