“Hoverboard”: xkcd: Hoverboard
To fly, repeatedly hit your up key. This thing is huge: I believe it includes a scaled-to-the-characters Imperial Death Star.
P.S. there are hidden “holes” in many of the black areas.
Goddammit. I have work to do.
It took me awhile to know you could go straight up. I’ve seen a map of the thing, and it seems everything in the air is mostly on the right side. I liked the X-Wing filling up with gas.
Hey, a Star Destroyer!
Found a pic of what’s believed to be a full map of the play area: https://i.imgur.com/uYryxss.png
How do I enter the holes? I keep bumping off them. Eating all the dots didn’t help.
where the hell does he find the time to do stuff like this?
I’m not certain but I think at least some black areas are one-way holes.
URGH! :smack: I meant Star Destroyer.
I keep getting stuck inside the Washington Monument.
I don’t think they are supposed to be one way. I’ve found to get out keep pushing up and left and/or right a few times.
There’s supposed to be a secret lair under the volcano, you can see it in the map, but I haven’t gotten to it yet. There’s supposed to be a total of 169 coins, I got 159 of them the last time. I’m guessing most of the last 10 are in the lair.
I suck at this kind of thing. I didn’t realize you had to keep hitting the up key, so I never got out of the start area.
Well, that explains why my xkcd iPad app kept crashing this morning when I tried to see the new cartoon.
ExplainXKCD tells you how to find it by going through the lava. I found it much easier if I used “Goggles Mode” as documented on that page.
The sky doesn’t seem to have an upper boundary; you can climb without any limit I’ve found and the drop back takes correspondingly long.
I got stuck beneath the surface… all black and I don’t know how to get out. 
I found the ball pit in the star destroyer. It’s up at the top near the front.
I cheated and used the map. 
Oddly, the Star Destroyer is laid out logically enough that it could be divided into four main sectors, connected by a few critical fore-and-aft passageways. With direction signs at junctions you could find your way around fairly easily.
Yip, which is why I found absolutely nothing. The OP says to keep pressing the up key, so I did for about five minutes, wondering when I’d see something.
I just think these things aren’t for me. I almost never find secrets in video games, either. Exploration in this context always seems boring to me. It’s why I hated the first Zelda game, too.
I found Artax, the horse from The Neverending Story slowly sinking into lava… snif :’(
