This was a very cool game for a lot of different reasons. Obviously, I'm impressed with the art direction. I think I would rather die than create so many animated assets in a hand-drawn style like this, and your dedication made a really stylistically-distinct game. The intro cinematic specifically stuck out to me a lot. It seems like a nightmare to get that functional in RPG Maker, and it adds a lot to the game tonally. Sometimes collisions are a bit awkward because the character is so large compared to what RPG Maker wants, but nothing felt impossible to navigate.
(On that note, I got stuck on the first map because I couldn't tell where I was meant to walk out. The tree I had to walk behind seemed like it was meant to be a collider, and I thought I somehow hardlocked myself.)
The writing is pretty well-done too. It compliments the tone of the game and its graphics really nicely. You managed to mix the somber introspection perfectly with the projection and theorizing on the bones, and somehow it felt like there was a deep connection between the protagonist and a dead girl that she'd never met. The line about wondering what her skull looked like was one that stuck out to me a lot.
My only real criticism is that the chase scenes kind of clash with the well-constructed tone of the rest of the narrative. This game's slow, contemplative pacing is its best quality, and the sudden bouts of fast-paced, high-tension gameplay and audio detracted from that quite a bit.
Other than that, I really did like this entry. It has a very clear goal running through its art, its audio design, and its writing, and it accomplishes this goal incredibly well.
