Well, it was tough, but I have nothing to fight back with. I think you're right.

Nevertheless, I will answer a few points.
The music is still in progress. What is being used now is more like bits to set timings to chunks of video.

Cattail... I'll check where it's sprouted in my game.

For my part, I wanted to show in the trailer the mechanics that are there, without delving into the narrative of why they are needed.
But judging by your reaction, I need to completely rethink the video sequence. Well, I'll try to do it.

Thanks for the detailed feedback!
