Curiosity is fine :D Unfortunately, I am nowhere where I would want to be in terms of progress.
C4 is a bunch of disconnected bits and "WRITE THE OPTIONS" and "CODE THIS" bits that need all be woven together and things filled out. And there is a ton of writing still to do for the actual content too, not just connecting things. I don't have a wordcount to give since there is stuff in twine and several bits in word etc.
I know this is probably not something that anyone wants to hear, myself included, but honesty is good in my books. I work on it in in my free time, but after C3 I have also 1) started new studies 2) started a new job. So real life has been intruding a bunch on said free time. So progress is slower than wanted.
