One noteworthy difficulty concerning the walkthroughs on NicoNico is that a lot of them are using the original Japanese Hack9 engine. The English translated Hack9 (and in all likelihood the presently available Japanese binary as well) now use the Hacker9 engine. The difference in what happens with the physics probably has little to no bearing on the practicalities of the game, save that it’s perfectly possible to push a useful item into a spike pit.
This Spoiler-ridden scene of depravity begins right at SPIKE HELL, the area I’ve only just recently beaten. The thing that makes it rather remarkable to watch is that in this version of the game the bullets from the tanks break the blocks above that one is eventually expected to traverse after enduring two screens worth of the most hatefully nerve-wracking game design I’ve ever witnessed. That said, it probably won’t affect the veracity of the walkthrough even on the current build of Hack9.
Unfortunately NicoNico’s approach to streaming is miserly as all Hell so I have to watch this same stressful area repeatedly in hopes of extracting a clue as to where I need to go next. The commander said something about a “PDA” (maybe a story element? maybe not. I haven’t paid close enough attention.) that I need to reach having successfully delivered him the C source code found at the end of SPIKE HELL. I’m definitely stuck on 2F until I figure that out. A brief examination proves rather conclusively that 3F is wholly inaccessible at this point.
Somehow I feel as though a boss may be a likely appearance in my future.
edit: Somehow I think I actually do know where I need to go next. It’s a screen that inspires such intense dread and frustration that I seem to continuously forget about it. One floor below the SPIKE HELL entrance in 2F is a room called TRIPWIRE. This room is full of breakable crates, a few of those moving blocks that cause damage, and these strange patches of white, webbed nonsense. This is the part I need to refer to the Japanese walkthroughs for a solution to, because looking at it straight on there is no apparent way to traverse it without making contact with one of the white blocks, which automatically warp you back to the transportation tower inside of the Battleship.
However, the player in the video from the last post seems to enter it in the later half of the run length of that vid, so I guess I’m about to see the solution. For the sake of sparing myself the NicoVideo load times in the future I’ll probably try to describe the method of getting through via spoiler text in an edit to this post.
