I really love the direction you went in here, and it's really impressive what you've managed to achieve! You've made a lot of really smart choices with the visual and sound design, and it comes together into a really cohesive and atmospheric whole. The 2d characters on 3d backgrounds works really well, the sounds effects as you run around collecting wood are fun, the music and the pipe noises are the perfect type of creepy, the dialogue manages to pack a strong storytelling punch in a fairly small word-count (and I really liked how game control prompts were "disguised" in text), and the simple mechanics of managing your body and fire heat give purpose while setting the scene. I agree with you that the current version is already a polished and releasable product (more than a "minimum viable" one in my estimation), but would love to see the additions you've suggested and then a price tag on it.
In terms of your itchio page, your trailer and promo images capture the vibe of the game very well—and as a consumer, if I stumbled across the them on steam I would be inclined to buy the game!—so it'd be great to see a banner and background added to reinforce the overall visuals.
In case it'd be useful, here are the bugs I encountered while playing.
- I accidentally clicked on Kat a few times after talking to her for the first time, and the game stopped letting me interact with anything or move, and I had to reboot it
- Upon reloading it wouldn't let me select any dialogue options with Red-Eye and I couldn't back out of the dialogue, so I had to reload again
- On reloading this time, it displayed Red-Eye's name as "NPC" for a few bits of his dialogue
- The game crashed just after the credits, so I'm not sure if we find out what's in the pipe
