It's practically not the same game anyway. Runs from before 2.0 should probably not be on the same leaderboard.

Simple search and you can find 1.0466 (the version that the guy used).
Next to their run, the version says 1.0466.
Let me check the run real quick.
EDIT: The guy did use 1.036, you can access that version here: https://javasnake.neocities.org/cookie/
Quick note about the difference in golden cookies between 1.036 and 1.0466:
In 1.036, the chance of a golden cookie being a Click Frenzy is ~2.44%. In 1.0466, the chance of a golden cookie being a Click Frenzy is ~4.76%.
The time for a golden cookie to spawn in 1.036 ranges linearly from five minutes to fifteen minutes. The time for a golden cookie to spawn in 1.0466 ranges in a cumulative normal distribution from five minutes to fifteen minutes.
In essence, this means that playing in 1.0466 is just under twice as likely to yield a successful run, but a successful run in 1.036 is generally much faster.
So I guess we need to decide if I should remove it entirely or add 1.036 to the version list. What do you guys think?
I'm biased, but I'd, of course, like it to be removed or relegated to a separate category. My personal opinion is that only version 2.0 and above should be allowed (or 1.0466 and above, as that's still accessible on the official website and it appears that it will continue to be for the foreseeable future).
