This one's really good. I love the feeling that you're building towards something greater in the game. It's very fun to watch the number of resources you get per second go up as you build more resource extractors.
The start of the game feels a bit confusing, because the user interface is misaligned slightly for how many resources you need to build things. It took me a while to figure out what the numbers are actually corresponding to. But once I did, I enjoyed it a lot more.
More musical variety would be nice.
This is one of those games that I'd like the ability to save and come back to later, so that I don't lose my progress. But other than those, I enjoyed it a lot.
