Really like the art system. I think it's cool that you used your game to convey a message that you care about. I really love the featured image of the game. Very nice. I played it on stream and had a good time doing so.
I agree with ION, that mini-games would benefit from a small explanation in the beginning. I failed the first one of the papers because I didn't know how to do it the first time. Not a big deal because then I just did it the second time. Another thing that he touched on was that was interactable need highlighted or something like that. I agree. I tried to talk to the bird people in the plaza and nothing happened. I thought, maybe they are for a later step. Then I got to a later step and thought, "oh! This is where I talk to the bird people", but it wasn't. Again very small thing, but it would be nice if it highlighted or something like that. Or if they just had random dialogue that was like hints or something.
That said, all my feedback is really nitpicking. It was a good game, and I would love it if you could see this story/convey this message over a longer more nuanced game. Thank you, for a fun play-through!
