Relevance of 'Too many files' for Itch?

Hi everyone,

I posted my project on itch.io and ran into their limitation for max amount of files.

After talking to their support (and getting the cap raised) I was given the recommendation to try working with sprite sheets to avoid producing 'Too many files'.

Now I wonder if the amount of files is really something to consider - not that I actually intend to rework my project in that regard - given that my html project is only around 14mb right now, I dont feel too bad about it. So what's the impact of a 'large' number of files, if I were go extreme? And about where would that start?

Thanks
