Hey there,
For puzzle 15 (quickSort), the capitalisation caused an unintuitive experience and the count displayed "incorrectly" for revealed words. In my case, I tried 'quicksort' as a first guess, which reveals the name of the function (stylised as quickSort), but counts as 0 matches due to the capitalisation token split. This was my first debuggle attempt, so I was a bit confused!

Additionally, the filename match did not activate, again as it's parsed as two words, 'quick' and 'sort'. I am not sure how is best to handle composite words as guesses / solutions, but maybe guessed words can be additionally checked against the full filename string and similar. If this is expected behavior though, or you think this would be inconsistent, feel free to close this ticket.
