Hey thank you! Glad that you enjoyed reading :)
For what it's worth I think that even getting a rubbish, rough-&-ready sketch helps a lot in the long run. I've had to work against perfectionism every step of the way, re-drawing and scribbling things all over, but it's helped keep us on track and syncronised.
If you're interested I just posted in the 'Mid-Jam Playtesting' topic with a link to the current build :)
Thanks again!
