I really love the hand drawing cutscene, a touched sad story. And the vaporwave music style is good.
The main character has a really good detail in differ direction facing. Reflect the bullet to the the shooter himself is not a new idea but refer to the story of this game is suitable.
(Spoiler: you have to kill the zombie to save the girl but the girl has became a zombie)
Somehow the "avoid jump" did not work very well, it can't get neither a instant movement profit nor enough invincibility frame for bullet proof.
