Hey! This is very cool! I feel like the character portrayal is very accurate to how people in our age group interact online, and I think the struggles of the characters were very relatable throughout. The leaves in the background and the music create a nice ambiance while playing that is not distracting, but makes the game feel more polished.

The ending was sad and impactful in a good way, and I loved the continuous stream of sponsored posts. It seems very realistic that these would continue to automatically post in the event of an actual apocalypse. I also think your decision to add more posts at the end, by accounts that seem to have been hacked is great because it shows the total meltdown of technology. The characters descent is appropriately chaotic feeling, and I liked the detail of everyone using a survival hashtag.
