You, sir, are entirely missing the point of both the game and the arguments against you.
The game is a simple simulation meant to bring that SCP to life, to let you experience the tests described on its page. It doesn't need anything more than it has, and I doubt the creator intends to expand upon it; I expect and hope that he moves on to short games about other SCPs.
Your arguments make no sense, largely for the reason stated above. Of course you are allowed to criticize the game, but you have to treat it like what it is; a quick one-man project to help illustrate a wiki page. If I started playing, say, Gears of War, and complained about the distinct lack of open-world gameplay and deep, emotional characters, I would be speaking as you are: undeniably correct in that these are features that the game is missing, and perhaps even features that would make it "better," but completely ignoring the fact that nobody expects them from this specific game.
But its not HARD to just add a limiting of the floor number, honestly my friend got to floor 100 before we just got bored of waiting and scared the shit out of him by hiding behind him in the dark and snorting like pigs or breathing on him (see that was fun as shit, could post a recording of it, no gameplay though because its irrelevant)) or something, and at that point he was so pissed he just quit
Edited:
I just think that this game was wasted potential, as in, it coulda been genius.
