Yeah, our tutorial was lackluster when actually explaining what to do. Thanks for giving it a try though!
If you're still interested in getting some fun out of it, I can explain how to play here:
Press the sun on the main screen to start (due to a bug, there's supposed to be a play button but it doesn't appear). Your player is the tiny satellite with the smallest orbit around the sun. You start off with nothing but a few resources, and to get more you need to upgrade your satellite in the upgrade menu (accessed from the top-right). There are four types of upgrades: More probes, longer rope, faster mining, and efficient mining. To start you can buy one probe with your resources, and a rope coming from the player will appear. It follows your mouse and when you pull it too far it becomes taught and can go no farther. By clicking on a planet you can attach the probe to it and start mining, but be warned! If the probe goes out of the ropes range while attached to a planet, the probe will be destroyed. The goal of the game is to get some upgrades and mine the sun. If you break all of your probes and cant afford more, that's how you lose.
