Hi FullThrough
To start off, thanks for making that video. I'm glad that you found Node connect interesting enough to make a video on it.
Regarding your feedback about the reference sheet. From what I've played and tested, most people would need it for several seconds, and pressing the "Tab" key once to open and once again to close it will be a bit inconvenient. This why even in the tutorial you have to hold the "Tab" key to open it.
But if more players would like the reference sheet to be toggleable, I would gladly add this feature.
Thanks for playing
