I really liked the game you guys are making. I am still wondering if the "there is only one ending" in the description is a meta red herring because the end is kind of gasping and urges a "I want more" feeling! As the imersive indie storytelling you are aiming, I surely will keep an eye in your future work in this project.
I am also a indie dev wannabe and makes me pretty happy to see two guys, in their spare time and using all the tools available (Godot, freesound, etc etc) to make their dream tale to came alive.
The art is beautiful, both anime-style and the pixel art. The sound and music is greatly made and/or assembled by you. As gameplay wise, I think the game uses well the "walking simulator"ish design to introduce the player to the world and their elements. And, lastly, I really liked the multiple perspective introduced in the avalable maps - the top-down view in the majority and the lateral side-scroller cramped door corridor. This two together make me think of both of classic Horror JRPG/VisualNovels and the Lone Survivor indie horror game. I think you nailed the vibe in this demo! Congratulations, again :)
