No, it hasn't been fully translated yet. It's almost playable, but I have difficulty translating the remaining parts because they contain lots of Japanese idioms, and I'm not sure how I should translate.

Hmm, my stage 2-2 translates fine, but that might be because I went through all the dictionary files and corrected the errors. Not errors with translation, but positioning of text. What has to happen, is that the text on the line before the tab in the file has to be exactly what the game says. No extra periods, commas, or even spaces. And no that's not what I want, that's just what the game needs to work. Once I proofread the new translation updates that came out a couple months ago, I'll pm the developer with the fixed files. And yes that will happen soon, summer school ends tomorrow so I can probably get my Bokurano Daibouken 3 walkthrough finished, as well as The Blank Game and translating all those menus.

and allso  ad more nice tracks   and plese main  thing is  translet that read me to english plese

Insects fly, so that wouldn't make sense... and google translate has been attempted. Idioms don't cary from language to language... that's why they're so tricky to study. If I didn't work at a Japanese company where I had to use the language every day I likely wouldn't know half the idioms I do.

I know some of the insects do, but the ones that launch needles sound more like they hop.

Regardless, they should be able to fly to different levels of the stage if that's what they're doing.

I didn't expect the idioms to translate perfectly by any means. I just thought perhaps they could suggest an equivalent. The only things that I've seen absolutely not translate are human noises, such as when laughter is emulated in various ways via the synth, or cries of pain or surprise.

It definitely seems like a matter of personal preference. I don't like being able to climb up to a higher level of the stage and then effectively have nothing to do accept hold down an arrow key while I can hear enemies below me. This means that in order to train my stats, I must stay on the lower levels, whereas if enemies could spawn on higher floors of the level, I could explore and gain experience at the same time. Plus I think it makes some levels too easy and makes enemies spawning on those levels pointless if all you need to do to remove the difficulty of the level is climb a ladder.

I like that in stage 8 level 3, the minidemons can climb trees. This mechanic should be used a lot more in the game to make the upper coordinates of a stage more exciting.

As for the enemies' climbing capability, I avoided using it too much because the algorithm was very complex and sometimes they went in completely wrong directions. The Each AI scans the entire field and decides the tree or ladder to use in order to reach you, but it seems to misbehave for some reason. It happens very rarely though, as the field gets more complicated, you may see more enemies stuck at the unreachable positions. If I could implement, the limit would be somewhere between stage 8 or 9, unless the cause of the bug is spotted and fixed.

True, it may be easier to avoid enemies. But what you forget is that there's no point in avoiding them because that's a lot of wasted xp that has to be regained by grinding later. but I agree, that would definitely be more exciting... though trust me, if you play the game on higher difficulty modes and try doing the same later on, it's not going to work out nearly as well for you. I think early levels should be easy, and many other games also give you the option to avoid enemies or climb to areas they can't reach you. But both are good.

I know that Yukios been pretty busy with the game translation/college life and all that, just curious as to the state of bk3 2.0. Is this still planned to happened? Or are you absolutely sick of dealing with BK now. Either way I love all the work you've done with translations, thanks tons!

I do not like to say anything empty or avoid constructive arguments with obscure statements, so I'll write down what I'm just thinking right now.
As for the answer that you probably want to know the most, it's "Yes, something will be released, but I'm not confident enough".
A little bit of implementation-related things first. Since I wasn't coding the game with translation considered when I first released the Japanese version, the source program had to partially be rewritten. I think I've done most of it though, very small snippets of codes sometimes require fixes, replacements or reorganizing. That's why you are sometimes notified about the software updates. I've just recently switched my project management to Git and split the V1 and V2 source codes by branches, but both are currently conflicting because I have already implemented some elements on V2 source, which still doesn't have translation-related fixes that I previously mentioned. I haven't tried auto marging though, I highly doubt it will work because the changes are massive in particular functions. The only choice left is to complete the translation first then start migrating the V2 changes to that source code manually. For this reason, while I'm working on fixing translation bugs, I cannot code anything related to V2. Under this circumstance, I cannot announce any release dates or plans other than the translation project currently going on.
As you might already know, I'm an audio game developer but also a University student who is researching internet and accessibility at a lab. Also, I'm developing utility applications with one of my friends and I'm writing most of the backends of them with C++. Although these do not necessarily mean that the time I can develop was completely stolen or I am less motivated to game development itself (I think I actually have time more than you would expect), things I want to or need to do is increasing.
While all of above are great opportunities for me, it is also true that I'm starting having a dilemma about audiogame development. As I gain experience without losing interest in audiogaming, games I feel like developing are growing so crazy that I cannot even imagine how much resources and time is required to complete them. These kind of thoughts usually screw up my mind; I'm unable to evaluate if they are really fun once completed, or more basically, if they are realistic in terms of playability, implementation, cost and any other perspective. Although it is obviously possible to post a topic here about one or more of that, it must be personal evaluation eventually because that is what a developer needs for keeping his or her project ongoing in my opinion. I haven't talked about this here though, I've tried initiating some new projects in last few years. Sadly, at least three of them are stopped or almost abandoned. And still, incomplete, inadequate and sometimes ununderstandable memoes are scattering everywhere on my harddrive.
Talking specificly about BK3, I have to admit that I feel like leaving from the series and shifting to new one. This is mostly because there are too many things that don't make sence in the story line or character settings. Although I understand the idea that the story is not the main element of games or it's like a tiny bit of spice, I cannot see it colapse anymore. That being said, I remember I've stated that I am going to release the V2 X and disaffirming what I previously promised is a thing that I hate the most. I haven't lost motivation to release V2 X, but not sure if it will be paid or reach the level such that you might be expecting.
I ask myself: "So, you said you wanted to shift to another series? Then, does it mean you will develop a new RPG? Action? FPS? Multiplayer? Racing? Fighting? Flight sim? Gunfight? You have some ideas?". And that rewinds me to the previous paragraph.

A very honest statement and well written one, Yukio. And one which explains, at least to me, why Japanese audio games are so good. This is a thought process that, from the evidence provided, doesn't always seem to be part of the thinking of some of the developers in this community, who are simply concerned with releasing as many games as possible and often let things fall short in terms of quality because of that. Do what you need to, and take your time. The BK series has been a great one, and especially 3, even though the story isn't a perfect one with things that don't make sense, it's still a very entertaining ride. Story can indeed be the main element of a game if one wants it to be, but most people who play BK 3 realize that the action is what it's about, and the story is definitely good enough to make most players want to keep playing, I would imagine. It's certainly deeper and more imaginative than anything else in this community at the moment, and isn't just about robots and monsters. On a basic level, the BK 3 story, though simple, does have some good messages in it.

As for resources and the like, as CJ89 already said, it's a common problem. But the fact that you're thinking about these and considering them when you think about what games you are wanting to make, it'll help you not to reach further than you can, and so can make realistic goals and deadlines for yourself. Whatever the next big series from you is, I'm sure that it will be amazing, as well!
