Love the vibe when the drums kick in. The melody from (0:09 - 0:15) feels like it wants to keep going in my ears. The drums coming in and out feels a little random, too. The overall unsettling but mysterious atmosphere sells it, but the structure to me is a little confusing. Really cool harmonic progressions you've come up with, though, I think you're on to something!

This fits the picture so well! The slightly joyful bop which turns into this spooky theme, I love it!

I love the spookiness and the melodic-percussion. Super fitting to the setting!

I genuinely enjoyed this one, I could see it in a unique, off-beat metroidvania. It has just the right things to make it stick out as a soundtrack. Great stuff.

Nice. Plenty of variety behind the main motif. 

Personal preference, but I felt the high pitches could've been tamed a  little with an EQ. Bass and pads successfully provide an ominous undercurrent to the song (run child, you're about to be consumed by the purple monster!).

Kinda spooky feel to it. Nice countermelodies on that music box part! Those dissonant chords right at the end are super cool too.
