I'm Rob Rightmyer, the developer of Threadbreaker. I wanted procedural bullet-hell runs without making the player decode arbitrary noise, so encounters are assembled from authored pattern phrases with fixed warning time, recovery beats, and a preserved escape route. Gold geometry tells you what is coming; grazing charges Thread; Sever lets you cut a lane when the pattern closes.
Here is 15 seconds of actual play: https://youtube.com/shorts/H_WSqqr7AcQ

I'd value blunt feedback from experienced shmup players: do the gold telegraphs read honestly, and does Sever feel like skillful route-making rather than a panic button?
Developer disclosure: this is my own game. Its artwork and music include locally generated AI-assisted production assets, and the narration is my synthesized voice; the runtime encounters are deterministic authored choreography, not generated by an online model.
