Just finished my LD entry. Due to personal things, I only had close to 10 hours to finish this. And it shows.
I don’t think it impacted the code itself, but I had to run with the first idea I had. Which, it turns out, was not that amazing. I tried to polish a bit, improve the input, add some challenges, but that’s the most I could do with the time I had. 
If you care about some implementation details, check my blog post.
