Interesting game. I really like the visuals, and the general  subject matter, but it feels a little flat because of the lack of genuine player agency. The concept of "maybe it's bad to kill the thing" isn't a particularly novel one, and it feels sort of unfair to not allow the player to opt-out.

Also, I do think the part requiring audio should be addressed, either by adding on screen text or at the very least a warning in the description of the game addressing the lack of accessibility.

That being said, I'm interested to see more in the future.
