[~2014/15] [Android(?)] Minecraft-esque jailbreak FPS that's haunted me for years

My memory on this is faint, but the details I do have of it I am 100-million-percent certain are accurate. One thing I am certain of is that nothing that I could find just searching "Minecraft Cops and Robbers" or whatever had any resemblance to this game. I've been everywhere—the Play Store, Archive.org, YT—and haven't seen a thing. The Amazon Kindle tablet I played it on just had Android on it, so I'm tagging it as that and not "mobile" in general, because I'm not certain it was ever on IOS, and I wanna narrow this down as much as possible so others have an easier time searching for this than I did.

Now, a description: You're just a prisoner, trying to escape prison, and you have guns. That's really it. But I remember the game itself being so outlandish and, in a way, ethereal? The cops themselves were oddly massive—around two or three times the player's size—but went down with relatively few bullets, and the game played like some bizzaro GoldenEye 007 with clunkier controls. The prison was unbearably grey, and had textures similar to Minecraft's bricks, but recoloured to have a bright grey hue. The building lacked in shading in its textures and real lighting, making the already pretty empty building look even more naked. The prison guards, to my recallection, donned stereotypical blue outfits, usually sporting sunglasses and beards, along with their guns.

This strange thing was divided into levels, too (it never had any online play) though I can't remember what the menu itself looked like. I remember the app icon being rather generic: a prisoner weilding a weapon. It may have had that familar boring-grey stone background, but that in specific I don't remember. I've shared about as much as I can about the game myself, as the game itself was, in hindsight, rather repetitive in its goal; I'm merely searching for it, because this THING has haunted me for a good decade, and I want it found and this chapter of my life finished.

And now, a possible lead: N&K Creativ Team Szolgaltato Korlatolt Felelossegu Tarsasag. I'll shorten it to NKC for simplicity. Being in the lost media (games in particular) community myself, I've heard this name come up in a YouTube video (MJay's video on lost mobile games specifically), where it was associated with one Break the Cookie 3D, another mobile game of theirs that ended up being lost. And it was in this video I saw a scroll-down of NKC's App Store page which contained a whole five Minecraft-themed Cops N' Robbers games. It was here my want to find this elusive app was increased a thousandfold, and it was also here I made the hypothesis that, in this obscure studio's sea of cashgrabby games, the one I had been hunting for lies... and it's more than likely lost forever. It helps not that the video showed N&K's APPLE App Store page, implying that, assuming this is even the right developer, there are multiple versions of this game to be found across other phones, and both are so obscure they only survive in one picture with no clear answer on if said picture is even of the game in question.

All in all, I'm at a loss, with an uncertain lead. I'm hoping this will be found at all, if at least in screenshots/videos, and that I'm not alone in remembering this game. I have been haunted by this strage, almost uncanny game for over a decade, and i plead for any knowledge/corrections that may crop up. And, thanks for reading.
