This is honestly a very interesting concept / world to think about. I'm not sure what class this was for exactly, but I think this could definitely be expanded into a full game. For instance, I'd love to see how the protagonist/player can be challenged further, as this current build of the game doesn't necessarily give the player a moral dilemma as it is a survey of issues of the future (no way to "run out" of canisters and see the aftermath of those without). I also like how vague the instructions are to giving/denying canisters: are you supposed to give it to those who are struggle to live, or those who have the highest chances of living? Of course, those details probably should be ironed out in an expanded version, but it works well here.
I'm just letting out my thoughts, but I love the art and the small-scale, human lens to a large-scale issue/future!
