This was a cute entry. I don't usually like zombies, but this had a fun twist to it. The fetch-like quest was simple but entertaining and all items available unlocked a piece. It was also nice to see the different characters get a specific colour when they talked (though it would have been nice if the main character also had one too :P). There were a few comical moments during the story that I appreciated a lot (the sour candy stunning the zombie xD).
The text may have needed a bit of a grammar check, but this didn't detract me from the story at all.
Good job on your first Twine game!
