To be fair, that's not really 99 lines. I mean, you could make it only one line that way. And, while I'm gonna get a negative score, let me ask about what everyone has with the "Look what I made in less then 1 day or less then 100 lines." It just usually sucks and would have been better with more days/lines.
This was no "one-liner". The code was quite elegant and simple, and while without empty lines I didn't observe code cramming to any particular extent. Many lines even had small comments. I could sense that it was written to be small, not written to be under 100 lines. Had it taken 111 lines or 128 lines, I'm pretty sure he would have just adjusted the title accordingly.
