I do like a puzzle! Once you find the knack then it becomes pretty easy though.

I appreciate being able to take notes by highlighting things, although I would like to be able to hide things as well as highlight them.

I found it too.

It's a game or a riddle ?

I will admit, you did kind of stump me by throwing in the timestamps as a red herring. But a decent puzzle otherwise; kinda felt like a TED-ED riddle.

I wonder how it would look and feel if the visuals were updated, maybe with some pixel art or a flat 2D style?

I have found it! Interesting game. Although I'm not sure if it should be called a game... Well it is a game but not something what video games usually are. Interesting. Amazing work that you managed to make this procedural!
