the beginning arpeggio of "Witch Chorus" had me intrigued, and the rest of the track had me immersed in the environment of the game immediately! your instrumental palette works well and lends a particular vibe that coincides with what you were aiming for, nicely done!
i love the percussion of "Masks and Monsters" — a focus on drums always lends to good tension and high-action! personally, i'd want to see even more on how the theme can evolve and vary, since you mentioned that in your project page!
