I saw the Post Jam Jam on Discord and made an account just to comment on this game. Wow!
The game is polished, and the audio and art are good. What stood out was the writing. You've created a compelling world in such a short experience and the setting, the style, the dialogue show a great talent for writing. I finished the game in one sitting.
My only suggestion is rather than worldbuilding as a reward for finding an ending, maybe it could be something the player can find during the game? Like the part about souls being reborn, or Laura's motivation (all we know before the ending was she disappeared and we don't know why). I probably would have made different choices if I knew these things.
I'm excited to see you take this story and world further.
