I think I used a mental shortcut and assumed their reason was due to frustration because a fairly common context for sentences like the one in the comment I replied to is due to reasons of disagreement or dislike due to opinion, quality, lack of information, or some other reason.

The game gets kinda meta on itself. This is mild spoilers: There’s a greater overall plot that gets progressed by a looping simpler plot. The idea is that, you are instructed by a narrator to go to a cabin in the woods and slay the princess inside. The choices you make cause this plot to repeat with a twist. When the simple plot loops its influenced by what you did on the prior iteration of the simple plot. Each of these loops is actually you advancing down a branching story path, and you need enough of these branches completed to complete the greater overall plot.

Its sort of like the Stanley Parable, where you can defy the narrator, or go along with his demands. The fun is getting a reaction out of the narrator or any of the other characters by your actions or dialogue choices, and seeing the story change based on what you choose. However its still a visual novel, so its a lot of listening to dialogue.

I liked watching these as a kid. They played in the early morning before school. Sometimes the bubbles were just jokes or humorous observations. Othertimes, they were interesting bits of trivia in an age where the internet was still in its early days.
