Very good! I like that the menu becomes transparent when there are ores/collectibles below them. It is also just a really solid game which works great!

Nice game. My biggest gripe is that there was nothing to tell me that I had to press "E" to feed the goblin (nor click to mine, but that is more obvious). I discovered the "E" by accident, and had to clear another level so I could go, stand on the goblin again, and press keys purposefully to figure out what the accident was that had worked.
