Game Review: That Gravity Game

I don't know why I keep finding and reviewing games that take the basic platformer concept (i.e., the Mario games) and mess with it. First, Enough Plumbers (I later noted its ending); then, Hello Worlds!. And now, That Gravity Game.

In That Gravity Game, you play a marshmallow, Marsh, who was struck by lightning and brought to life.

Marsh isn't very lucky, because he falls into a machine called the Gravitron 3000.

There, gravity works differently than in most games (and differently than in real life). Within the machine, there are fields that shift your personal gravity.

It's very easy to tell which fields do what, as they are color-coded and have arrows pointing in the direction of the exerted force (i.e.the direction you'll fall in).

As you can see, you can fall up...

...and also sideways.

Sometimes you fall in every direction in rapid succession.

Like Hello Worlds! and Enough Plumbers, That Gravity Game is a puzzle game at heart, and sometimes, it's quite clever.

And like those games, it can also be quite vicious.

As with the other games, That Gravity Game is short and to the point. If you've got a bit of patience for the rough spots (and love a bit of cool music, which speeds up as the game progresses), you could do worse than playing it for half an hour to an hour.

Hmm... Distraction!

Look! A cool website!

(Runs away.)

I expected to have a certain amount of time to work on a certain kind of blog post today, but didn't. (Certain people's schedules changed.) Enjoy the website if you're interested. And if you are, you might also be interested in the program Celestia, which was really cool as of a few years ago, at least. (Being an open source project, it might have changed.) Celestia is free, by the way.

Ten Things About The War of the Worlds...

...which you may or may not be aware of.

1. H. G. Wells introduced his version of the Martians in an earlier story called "The Crystal Egg." Whether he had intended specifically at that time for the Martians to become invaders in The War of the Worlds is not entirely known; certainly, this story did not directly foreshadow the invasion. The titular "crystal egg" was used by the Martians (along with a number of other unknown "eggs") as spying devices. Each egg was linked to an identical one on Mars, and in the right lighting, certain individuals could see Mars in the egg. (It was a rather Lovecraftian story, actually.) The same year, Wells also published "The Star," which offhandedly mentioned that Martian astronomers had witnessed the events of the story (namely, the formation of a new star and its near collision with Earth, followed by this star plunging into the Sun).

2. The Martians' tripods were probably made primarily out of an aluminum alloy, based on the fact that the Martians were busy refining it out of local clay in one of their bases. Certainly, they made heavy use of the stuff. The fact that they could effortlessly refine it out of common clay is one of the few areas where Wells' Martians still far surpass us.

3. Mars is a dead world, but it may be considerably "less dead" than one would think. Note that I take the following statement with a grain of salt, but it's a highly interesting possibility. Some self-appointed "Mars expert" believes that Mars may have harbored a living civilization as little as a few tens of thousands of years ago (give or take). Why? There is evidence that a large body of some kind may have come within Mars' Roche limit and shattered, thus bombarding the world with thousands of meteoric bodies and utterly wiping out life on its surface. (The same guy suggests that three particularly large impacts linked with this event created Olympus Mons and two other large extinct volcanoes on Mars' surface. Of course, Olympus Mons is supposed to be a really geologically ancient volcano...)

4. The War of the Worlds is part of the period genre from Victorian/Edwardian Britain called invasion literature. Britain was really worried at that time about some country slipping past the British Navy and invading the British Isles. While the British Army was an efficient force, it wasn't much taken seriously by the European powers; Chancellor Bismarck is said to have remarked that, if the British Army landed for an assault on Germany, he would "send the police to deal with them." Europe's armies were far larger and more powerful than Britain's, and both sides knew it; thus, Europe dreamed of landings, while Britain had nightmares. The most notable novel of the genre other than The War of the Worlds is probably The Battle of Dorking, whose name I am not making up. It is thought that the main reason Wells had knowledge of then-modern military tactics and technology is because of familiarity with the rest of the genre.

5. It is not a coincidence that Dracula was published only the year before. Imperial Britain was well aware of the fact that its position was rather precarious in the world, held in place only by the incomparable British Navy. The Navy was required to protect shipping from piracy by other nations, to keep order in the British dominions, and of course for self-defense. These things were the lifeblood of the British Empire. Britain's fascination at this time with vampires-Dracula and the Martians-was because it was well aware that it was essentially itself a vampire feeding off of its colonies.

6. As with the later "The Land Ironclads," Wells successfully predicted a future development in warfare; where in TLI he predicted tanks, in TWotW, he predicted the use of poison gas, which like the tank became a fixture of the Great War years later. He also predicted the use of "total war" tactics to some degree, although this may not have been as intentional.

7. Cannons would make incredibly impractical devices for launching objects into space for a huge variety of reasons, including difficulty in aiming over such distances and the amount of acceleration that would be required for such a launch being lethal to any living thing and strenuous on even the sturdiest of equipment.

8. Well, let's be frank-the ending of TWotW was great in its day. But it's horribly dated, too. That bacteria would somehow fail to exist on Mars is absolutely preposterous, Martian science wiping them out or no. It's not so preposterous that their immune systems would have difficulties with Earth microbes, but if the Martians were truly so advanced, they would have been able to protect themselves somehow. (This becomes even more ridiculous, really, in Spielberg's version, since those Martians are clearly as much above 21st century humans in terms of technology as Wells' Martians were above 19th century man.)

9. Many people describe the Martians as being "invincible" to the British forces; while they were close, they clearly fell short of this, as a well-placed artillery shell could kill one. (That was why they started using the Black Smoke, since the heat rays would have taken too long and possibly have been too expensive for killing all the artillery they might encounter.) This meant that the tripods were at a minor disadvantage in the water, as ships had more and better artillery and greater mobility than land forces; of course, they were even more vulnerable to the heat rays. A naval ship proved able to kill two Martian tripods, though, so the Martians would have had difficulty leaving Britain, had they not been building flying machines.

10. There was a sequel. But Wells didn't write it. More on that tomorrow.

Size Discrepancy

It's kind of funny how little super robots usually get to beat up on big ones. Of course, this could be because they're at waist height (and thus are allowed to go for low blows).



The other reason, of course, is that sometimes they get bigger weapons than the big ones.

The sad thing is, both the bigger robot and the missile are proportionately far smaller than the originals, and that would still have happened in the series.

Super Robot History: Landmarks of Audacity

Robot with the best name: Xabungle. (There's no series information there, but it'll still tell you more about the series than Wikipedia.)

Robot with the most ambitious design: GaoGaiGar. (What could possible be more ambitious than a robot which takes common elements from preceding series [a train robot, a drill tank robot, and a lion robot] and crams all of them into a single design? GaoGaiGar isn't the handsomest mecha out there, but as my discourse upon him should indicate, the design has grown on me. Except Liner Gao. Replace that with a rocket ship.)

Robot that most radically defies physics: Tengen Toppa Gurren Lagann. (That robot ought to collapse into a black hole larger than a galactic core merely by thinking about existing, much less actually existing. Considering that its dimensions render it thousands of times larger than the Milky Way galaxy by volume, and it's probably supposed to be mostly solid [as opposed to the vast voids of space] it's probably as heavy as the freaking detectable universe. Not to mention the fact that there's no way a structure that large could exist without bending and warping in on itself, or that the robot's punches would be constrained by the c limit [that is, it'd be impossible for it to conduct a battle in a human lifetime, or even the typical star's lifetime, especially when you consider the time dilation that would be created by the robot's gravitational field], or the fact that it'd be ending all life in the universe by yanking their planets out of their orbits to itself, shredding galaxies, etc., etc., merely by its presence.)

Robot that was the most horrible killer: Ideon. (It destroyed the universe. 'Nuff said-Cosmos doesn't hold a candle.)

Robot that isn't really a Super Robot but deserves an honorable mention for being a greatly loved character and all that: Optimus Prime. (Yes, there's irony in this being said after yesterday's post. Also, to clarify, making that picture wasn't really responsible for the post being so short, I just thought it was funny.)

Catch It!

I was trawling around on YouTube, and found this video.



BRILLIANT.

Because it makes perfect sense for a missile not to explode just because a giant robot caught it.

And, oh yeah, nukes can't destroy more than a city block or harm human beings.
