This one is better than the extended version, maybe due to mixing changes - or it could be the melody repeating too much.
Something about the timbre, or maybe frequency of repetition of the melody just doesn't sit well with me - it grates on me after a while. I understand the choice to use dissonance to make it "uncomfortable" - but repeating it too much could simply tire the listener, not just make it creepy/uncomfortable. I mean, it's the same 7 notes (4 notes descending, then repeating descent from first note, with what sounds like a slight alteration), only modulated to adjust to the changing chords. It doesn't help that it's all at the same volume (other than the fade out), constantly vibrato, very short, and plays very fast compared to the background, other than the chords. Maybe adjusting one note on each repetition would help (other than to fit the chords), or maybe simply making the instrument itself sound less sharp would do the trick. And thinking about it - it may be due to how it doesn't blend in well with the rest (it's nearly pure sine sound, while everything else is close to white noise) - if it stands out, you generally want it to offer greater variety than the rest of the piece - and it's actually what seems to have the least of it.
Otherwise solid, with rather interesting choices for the background (lo-fi strings, something that sounds like white noise, a regular alert-like sound barely peeking through the rest, and vocal/choral-esque noise later on). I used to work with sound samples of about this quality when I started, so this certainly brings me back a long while - and I sure heard that FL Mobile isn't the greatest in that regard (part of why I never got it), so all is good there :D I can definitely see this in a spooky scene, though with the melody remaining as-is, I wouldn't want to hear it for more than a few minutes, thus only 3.5/5.0.
As an aside, I know I can get super picky/critical, but I always do my best to bring in pointers for improvement (and that's how I get long winded, too, lol) and I will usually point out what was done well, too :D I prefer to receive thoughtful comments/reviews, and that's what (I hope) I dish out, as well! Whatever I say, there's only one way to improve: keep experimenting and creating more! Cheers.
