Thanks for the feedback! I'm not very familar with the the subject of the second half so I sorta focused mostly on the first half - hopefully if I try this again in future, I can connect things better!
I know that in my case at least, a disproportionate part of the work was done in a mad scramble in the last 10 days. So I can imagine that losing several days during that final period really made finishing a lot harder. Still, an intriguing and original project.
