Yeah, like I said it's experimental and it's based on your imagination.

I'm fine with experimentation and I guess I'm OK with games that have no gameplay in them but I think it would be improved if the other components worked better together. Maybe if you replaced the dialogue with something relevant to the situation, even if that also appears as text rather than audio, it might work better. The blue-screen also pulls away from the feelings you are trying to invoke in the viewer. Replacing it with something connected to cremation might help.
If you wanted to develop this idea further, my suggestion would be to give the viewer the illusion that pressing buttons or keys will help them to escape the furnace. Maybe even respond to the inputs by telling the viewer that what they are doing is not helping. That would amplify the feeling of helplessness in the viewer.
