Well, this a little bit personal. My little brother died on a hospital bed, so your game made me cry right away. It's impressive that things like video games or other forms of art can convey or provoke these feelings. It's a ballsy entry for a game jam, for sure. It looks like you achieved something huge. I mean, in a very limited time you managed to create an experience, tell a story and convey a meaning. Most of all: to connect with people.
Now, on a more technical side of things, nice art style. Solid ambience work (in terms of decoration and sound work). What else is there to explore? Maybe if you read the story, be able to read the story. Being able to touch or hold the hand of your loved one could have been good (it's an important part of linking with them in that scenario, it feels like the most important connection you can have with them and in the end, it's one of the things you miss the most).
Anyway, thank you for pushing video games to be more. Game jams need more of these entries.
