the official design is boring, the story is sloppy and full of shock value instead of horror. I'll try to give some constructive criticism and suggest a better way to go about writing the character if I were to rewrite him, I would make the story center around how scared Alex is being trapped in a video game and not being able to feel anything. Instead of killing for pure enjoyment he would lash out due to his own fear and underestimate his own strength in his new form, then in a panic he would transfer them to vessels to save whoever he just killed. try to develop the characters, don't just say "hey so you see this kid that you've never known about until just now? yeah so he's dead lol"
