Yes please! Thanks!!
I've cleaned it up a bit and uploaded it to GitHub, just in case other people are interested in it: https://github.com/joseph-e-k/itchio-utils
Updated: It now scrapes the stat block from each game's home page (genre, tags, authors, etc). The plain-text output was getting a bit unwieldy, so it's now a CSV (which you can import into your spreadsheet application of choice).
If by "description" you meant the full text of the game's dedicated itchi.io page, that's a bit trickier, as those individual pages aren't all laid out the same way so it's hard to get the script to understand which part is the description of the game and which part is other stuff. I'll see if I can work something out.
If you have any more feature requests, may I ask that you put them on GitHub (or email me at itchio.utils at gmail dot com)? I suspect other people might be getting notifications for this comment thread and I don't want to keep spamming them.
