Use arrow keys to move the TARDIS around and control its speed with the Throttle variable. The two variables in the top left corner are your coordinates in space (x, then y). To open the TARDIS terminal, press space. To get a list of all the commands you can use, enter "help". To close the terminal, press c (don't ENTER c, press the button on your keyboard. Sorry, mobile-device people, I haven't added controls for you.) The commands are as follows: help - Shows a list of commands. find - Shows the coordinates of every astronomical body in the game. teleport - teleports you to your chosen coordinates. It'll give you a chance to tell it where to go. I haven't added time travel yet (and I don't plan to anytime soon), but I do plan on adding planets and expanding the world border, which is 5,000 on both axis. If you go beyond that, or below zero, you'll lose control until you're pulled back into the play space, which won't take long. The reason why you can't go below zero is because (with the system I have), the coordinate system gets weird if any of the planets are below zero. Someday I'll make more commands, but feel free to suggest new ones. I have no idea what to add. Another update or sequel I'm planning on is one in which you can actually go onto planets and explore with the Doctor, and fight Daleks or whatever. (If you don't know what a Dalek is, look it up and you're sure to find out. I don't feel like explaining.)
For anyone who doesn't know what Doctor Who is, and henceforth doesn't know what the TARDIS is, here's a brief explanation. Doctor Who is a sci-fi show (the best one ever, at least until Disney bought it). The main character, The Doctor, "regenerates" into a new person when he dies... so he's basically a humanoid phoenix, but he can live way longer than 100 before regenerating. Right now, thanks to the episode Heaven Sent, he's a little more than 4.5 billion years old.... Don't ask. TARDIS stands for Time And Relative Dimensions In Space (or, as the Twelfth Doctor said, "Totally And Radically Driving In Space"), and it travels through time and space. It's also indestructible, bigger on the inside than on the outside (it's infinite on the inside. Citation: Journey To The Center Of The TARDIS, one of the later episodes in Matt Smith's last season). If anyone wants to suggest a new object in space, remix this project, delete everything inside the remix, and just share the costume you want me to add. I reserve the right to NOT add it, but unless it's inappropriate or there's something terribly wrong with it, I'll add it. I'm a little stricter with actual updates you suggest, though, (which you can do in the comments) because that requires actual effort. Don't judge.
