I really like the concept your going for so far, and the design is very apt too.
The lanky "adventure time"-ish style certainly fits the style of a stressed out young person, and the animation was simple but conveyed everything it needed to.
I felt the navigation puzzles where nicely intuitive and just really asked me to carefully look around and think, and it felt good when I got there.
Also on the point and click, I really appreciated the contextual tidbits about the characters past when you interacted with them, it felt quite diegetic.
The delivery game challenge was a little stressful, but I felt that suited the tone very nicely, and the mechanics where handled well, not too much button mashing, and the prompts where reasonably clear but still had a challenging increase in skill.
I did have take M8 occur 3 times in a row, which is a little immersion breaking, but I think quite fixable.
The last set of comments I have is that I think you used music and sound design quite well in this to give the emotions the weight you wanted to express them with, because I think without them it might have been harder to relate, but with them I felt a close understanding.
Finally, I enjoyed the nice simple riff of Space Oddity, well done on that.
Thank you for making this.
