I honestly don't think it's right to release the prototype cart as it is, although the Japanese version is beatable, you still get the feeling that the American version has some details that made the game feel so much better, and that is actually the more definitive version (I'm looking at you, Cheetahmen II: The Lost Levels). Remember how most people think censorship can take some things away and the original version is better? It's the exact opposite here as the gameplay still has some kinks in it and it's a lot more difficult than it needs to be because you're starving for health a lot of times. I know certain games have difficulty tweaks during localization, but this is absurd.
Although your theory on the Japanese version being a WIP prototype makes sense, I think that game is ironically the more completed version. I'm not saying this just for the heck of it, I can actually prove it. If you look up "Japanese Secrets Monster Party", you can see some pictures of the game during development, and one of the pictures shows the title screen. You can see that one of the screens shows the mouth being more smaller and you can see the eyes on the top, but that was changed in the Japanese version where the mouth is more open and pronounced. Not to mention, in the American version you may get an item if you visit an empty room.
The prototype actually has a couple of things the American version didn't have. In the Japanese version, the game freezes a bit when you get a key, which felt a bit more satisfying than the American version where it appears all of the sudden.
So basically, what we got is the older version of the game with some censorship. This made me think that the Japanese version was supposed to be released later, but it got cancelled. My best guess is that Nintendo of Japan themselves canned this game, because where else did the second buyer of the cart found it? In a lot near NOJ's HeadQuarters.
I was thinking about taking the American version and add the missing content as well as change some bits (like taking out the third boss in Stage 7 because it didn't exist in the original, it was added in the American version, not to mention it causes an annoying bug which makes the stage unwinnable), but I don't know too much about programming aside from changing the graphics, but maybe I can figure something out.
