Digger Game Asset Pack?

I've been working on this sideproject for the past couple of months and I'm running a little shy of ideas for tiles and textures.

Basically the idea was to make a texturepack for a digging-game, but I've been wondering about turning it into a game. I had some fun with creating a title for the game as you can see.

There's about 70 tiles / sprites so far, including:

• 19 resource types,
• 9 tiles of dirt, rocks, grass
• 11 items
• 4 buildings
• 11 surface details (rocks,trees,grass, clouds...)
• Fog tiles

So I'm curious, would anyone be interested in purchasing this from the Asset Store? Any kind of feedback is appreciated
