I have made a "Last Period" game, although I believe there is one bit not mentioned in the video, which caused the game to break upon meeting Mr Huang and Mr Castro, but which I rectified myself.
(You need to not just attach the releant conversations to Mr Huang and Mr Castro, but you also need to move these conversations to Panel 1 in the setup script.)
When I watch the videos again while making my own initial (basic) game, I think I'll make an aide memoire / cheat sheet so I don't need to repetetively watch the videos every thime I create something. I'll share this via e-mail with the support team, and they will be welcome to share this on the forums if they wish.
I did find a few bugs and bits of feedback and I'll post these later.
