Hey, this was fantastic, great job! Really enjoyed the prologue, and thought Chapter 1 took the concept in an interesting new direction (was feeling bits of Spirited Away, Yume Nikki, Undertale, The Witch's House, etc.). The story hook was also quite interesting and the two MCs have a good rapport.

The only real issues I have with it are basically similar to a lot of RPGmaker-type horror games. Sometimes the puzzles can be a bit obtuse, and it's unclear whether something is a lower priority secret area, not yet solvable, or important right at that moment (this might just be me, but I thought for ages that I was missing something with the ticket counter at the train station, trying out all my items, etc.). The puzzle design did get better as it went along though.
