The video has CC, so maybe that helps.
More context about the Tiptoi:
It's an electronic toy pen that you can use on various products from the same line. Books, puzzles, board games, even figurines. You tap the tip on seemingly normal paper and it magically knows what you point at and plays a sound.
The magic has been reverse engineered, and is a bunch of microscopic dots that form codes (imagine tiny QR codes, each 1mm²). The tip has a camera that reads those codes.
Additionally to playing sounds, it can set and read variables and branch based on these states. So you could say it's quite a bit like SCUMM.
This guy basically wrote an adventure game engine using the pen's limited instruction set.
