Okay, so I'm attempting to translate the text from an obscure Japanese Super Famicom game (for fun/general posterity). (This is not a translation or proof-read request of course - those are against the rules.) The game is "Olivia's Mystery" (オリビアのミステリー). The format of the game is a picture puzzle - you grab square cut-outs from a looping-animation picture (only mild animation, no sweeping changes across the frame), rotate them, and place them appropriately relative to the other pieces. When you've completed a level, some (Japanese) text scrolls across the screen, providing a narrative story to go with the images you're unveiling.
Here's the full text for the 8th level (which I'm working on), for context, with the pertinent paragraph emboldened. The broader context is, there's a water shortage on earth, this guy shot himself out of a human cannon (at a circus) trying to aim for a nearby country to get water to bring back to relieve the situation, but... overshot and wound up shooting himself to the moon (which has a breathable atmosphere somehow) (yes, this story has gotten absolutely bonkers). He's in some ancient, abandoned lunar civilization's city, and found a way to solve his water problems, but now needs to find a way back to Earth.
Now, here's the translation that I'm going with (for now anyway) up to and including the bold passage (extra emphasis added to final line) (some of my line breaks have been eaten):
Well, after a lot of searching, I finally found something that looked to do the trick. Just by the sight of it, it was obvious that this was a thing for flying. The reason being, it was shaped just like a bird. If this thing isn’t for flying, then what the heck is it for!? However, this machine was different from any airplane that aviation pioneer Mozhaysky might have designed, its wing-flapping design being a notable distinguishing feature. If you go to the land of the Nazca people, there is an enormous illustration - those with the leisure to do so should go there and see it of themselves. They are fairly distorted drawings, but the images are still fairly recognizable. Whoever drew them is a mystery. The machine I found, it could be compared to those illustrations, in its representation of a bird.
As you may have noticed, I added that final sentence pretty much in its entirety, based on little else than that the Nazca stuff did at least begin with 「なお、この機械は」. I must confess that this passage really baffles me - it begins with この機械は, and then absolutely nothing else in that section connects things back in any way (that I can tell) to that supposed topic that we just marked with は.
So now, finally my actual question - is this Japanese passage (the bold one) as strange and awkward to native Japanese readers (and any of you with lots of experience with the language) as it strikes me as being? Or is that initial 「なお、この機械は」 really enough of an introduction to the paragraph to more-or-less imply the "made up" sentence (or something much like it) that I made up and tacked on at the end because of how incredibly awkwardly it would read in English without it?
If it is really awkward, it wouldn't be the first instance. In the last level, when he's searching for water, it spends the whole time talking about how he's in an abandoned lunar city and how if he had more time he'd love to explore it, etc, and then wraps up with a terse "Anyway, finding an atomic water collector, I then set about the task of finding a way back - after all, he certainly wasn't going to find a return cannon back to earth!" (アトミック水くみ機をみつけた私は、水くみをまかせて、自分はかえる方法をさがすことにした。なにしろ月に大砲は、ない。). That one, I'm quite certain is just really awkward writing... but even so, this one feels so much more so!
Honestly, this whole project is such a weird mix. It often sounds kind of scholarly and sophisticated in spots, like the brief reference (before the emboldened section) to Mozhaysky (学者モジャイスキー) (apparently just assuming the reader knows precisely who that is), and in general some of the wording... and then lately this really bizarre stuff with overshooting himself with the cannon and winding up on the moon (so suddenly cartoonish a plot!), and the story itself kind of rambles around.
