Hi, great pre-alpha! The concept and implementation is solid. Ignore me if you don't want feedback, but if you're interested here are my thoughts.
First thing I'll say is - what makes this game unique? I love the base, but in my humble opinion you might consider adding something that these inspirations you mentioned don't have themselves - a unique mechanic, or a subplot maybe?
On a technical note, something that's a quick fix is z-sorting for the player character, which your game doesn't have (or maybe it does and it's broken) and I'd STRONGLY recommend adding as soon as possible (since it's so easy to do and without it the player's immersion is a little broken).
