UNDERHOLL - Trailer game

I've been thinking about making a small Undertale game with a different story, but first I'll upload some short trailers. I hope you'll give me your opinion and let me know if there's anything I can fix. I'm not very good at making this kind of thing. ¯\_(ツ)_/¯

Here's the context of what happened:☜(ﾟヮﾟ☜)
After Frisk, the main character (whose gender is undefined), completed the Genocide Route several times without ever doing a Neutral or Pacifist Route, something strange happened. After performing 17 consecutive Genocide Routes in the timeline, and on the last Genocide Route, called "23," Frisk resets that world's timeline again.

Upon reloading the reset timeline, Frisk falls back into the Underground normally, just like in the original story. But due to a glitch, the fall damage does affect the character, reducing their HP from 20/20 to 1/20. This makes Frisk realize that the fall really took its toll, and they see that the spot where they landed, among the flowers, is stained with blood. They also notice that their arm is broken from the impact, as if their body absorbed the damage in that area.

Continuing on, Frisk finds the area still littered with the dust of other monsters, the remains of enemies already killed in previous genocide routes. Flowey is there too, staring down at herself in her usual spot, but this time she's damaged or deteriorated. Noticing the player's presence, Flowey reacts defensively, becoming agitated and tense.

Frisk, trying to protect themselves because they only have 1 HP, decides to stop acting with a genocidal mindset and instead uses the "Talk" option in the Action menu, trying to calm Flowey down. After calming her down, Frisk asks her what happened.

Flowey explains that, because he remembers all the times Frisk reset the timeline and repeated the Genocide Route over and over, the entire world became corrupted. The game files and the world's configuration itself became more dangerous and unstable due to so many resets and repeated deaths.

As a result of this corruption, monsters began to merge with sprites from the Amalgamations in Alphys's lab, giving them deformed and disturbing appearances. Even the main characters like Toriel, Papyrus, Sans, and others were affected by this corruption… except for Flowey, who managed to avoid it by protecting his own files.

After hearing all this, Frisk and Flowey decide to help each other, and Flowey offers to accompany Frisk on this new, more dangerous route, embarking together on a kind of unknown journey within a corrupted world.
