It's a nice, simple little typing game the fact it references code and such is interesting and adds some flair to the game itself.  Especially for your first project it's a very well put together and straight to the point game.  A few bits of feedback though

• The word length, some of them seemed to be too long to display correctly which was a little annoying in trying to guess length.  Though since it happened to the very long words it didn't impact guessing the length too much.
• Disappearing letters, the fact that the letters you have input on words disappear is a bit annoying it doesn't impact it too much though it would be somewhat helpful to have them be grayed out.  Partially to allow you to know what the word is so you remember what to type, as well as to make it so the placement of the letters in the words don't change so you're not disoriented by it.

That was the most I could find to give feedback on, overall it's a well put together but simple game that, at least with your reasoning fits the theme quite well and with a pretty inventive way of looking at it, so far from what I've seen throughout the jam anyway.  Hope you had fun jamming and keep doing so!!

Congrats on your first game :) It's not bad, I think having sounds would be a nice improvement!

I love how you must type real variables and functions! I enjoyed it quite a bit!
