Hm, I would say it's a fun listen. One minor production issue I can see is that the sound effects you are using are fairly narrow, such as the chains at 0:31 and the laugh at 1:15. I feel like there could be enhancement of the stereo image without making it sound unnatural. To do that, one way is to add a ping-pong delay with a delay time of 15 ms or less, just so that you fool your ears into thinking that the sound is more stereo than before. You can do that with Fruity Delay 2 manually, or if you prefer you can try it with Fruity Stereo Shaper.
I like the lofi part at 1:20, and while I think it technically isn't too lofi as far as the fidelity goes, the muted brass does sound noticeably fake, particularly on the trills. If you stick to those samples, I guess what you could do is slightly lengthen the notes to overlap a bit more, and increase how up-and-down the alternated velocities go.
I don't think those two production issues bring it down though. It's mainly that the overall soundscape, to me, is more like how it would be if this were put into a remake of the game, rather than being an arrangement that puts your own twist on it (it's too conservative).
Still, I enjoyed this as it was, and while I wouldn't say it's currently ready for OCR, it's a good way to get in the mood for Halloween.
Nice and chill vibe you had. I will say the main pluck synth does sound a bit static; it could have used more motion, like with a filter LFO or a slight phaser. Same with the pads at 1:30, for example; the high reverb with the low frequency cutoff muds together the chords when a filter envelope (with a somewhat long release) to slightly open up the frequency range could engage the listener more. Other than that, a good listen.
