I am 100% certain. I even tested it with all of the characters, and they all get their jump height reduced by ~18 pixels running vs standing (except Sugar, whose reduction is only 9 pixels). You can try it yourself with the third coin group in the first level; it's easiest to notice as Yal since he ends up being unable to reach the coins at all instead of barely reaching them like the others:
I can record a video, too, if you want, so you can see I'm not releasing the button early.
Stumbled across more typos in the bestiary:
Also, I think the kill count for Soaker Girls and Water Balloon Girls are accidentally swapped. I have a save file where, of those two, I only killed Soaker Girls, but it was Water Balloon Girls who became unlocked in the bestiary while Soaker Girls were nowhere to be seen.
Oh, one more thing: I know this is counterintuitive, and I myself have made this mistake a few times, but it really is spelled "bestiary," not beastiary.
I was a bit rushed with my last two posts, so I neglected to mention that the last part of Mr. 44's entry is rather awkwardly phrased and kinda hard to understand. I think a better way to say it would be "to study the BROX's cognition, such as its combat ability and how it handles human interaction in real-life scenarios." The Oxford comma gets removed since the restructuring means there are only two parts referring to the studying of its cognition rather than three parts referring to the studying of BROX in general. Also, the shorter, less-detailed phrase gets moved up front since it reads easier going into the longer phrase rather than the other way around. Lastly, I rephrased the bit before "human interaction" to avoid using the word "ability" again so soon after its previous use (it's not grammatically wrong; it's just a pet peeve of mine).
Oh, and depending on what BROX is, you might wanna swap out my it/its for he/his. I just made an educated guess that since BROX is something artificial with prototypes, it could become either a male form (like Mr. 44) or a female form (or non-binary, too, I guess), but this is your story, after all. Also, I was convinced that BROX/Mr. 44 was a robot or something, but rereading the description showed me that there's not really much evidence to support that, so I'm not sure which pronouns would be appropriate.
EDIT: Rereading Dan Maku's description, I'd like to correct my previous correction to be "When he's" instead of just "When"
BROX is an (artificial) species name and an acronym* and Mr.44 just happens to be a male specimen. The sprites for this game is the first time I actually colored one (the existing concept art is pencil drawings) so I genuinely haven't thought of whether they're made from metal or Mr.44 just happens to be armored. In the original plans for Daemon Detective Tactics the BROX were meant to be a basic enemy that lived in sewer systems etc after escaping from the labs and becoming an invasive species (being a lab creation they lack natural enemies) but I never really went further than "okay, now I have a justification for putting Legally Distinct Balrog in my game"
* (it's never specified what the constituent words are, it's a reference to a super old unfinished Cave Story fangame named Tales of the Broxxus - which in turn brought back the rectangular enemies from the old beta screenshots, which is what the BROX species is based on)
