This is pretty simple: Hover over a planet to see it's data file on your hologram screen. Click a planet to go there. When in a planet, use arrow keys to move around. Click the SHIP button go back to the first screen. 's' to scan for gems. 't' to change scanner to laser drill and back. 'space' to dig. Click on gems to pick them up. 'i' to see inventory. 'o' to close inventory. Use gems to sporn a portal to the Cloud Galaxy to mine Rainbow Stone. Click 'Sporn portal' button to sporn portal. Click portal to enter. Feel free to remix, but give me credit!
This project is a beta, so some parts don't work yet. You can't enter the portal and if the scanner won't appear try digging first. there are also lots of 'cheats' because it is not finished.
