I liked the anime-like style you used for the characters, the music used was pretty good, the story (although short) was interesting and emotional. I really like these visual novel kind of games and yours are some of my favourites.
Maybe you could make a sequel with more choices next time? You know, following the ending where neither of them dies a horrible horrible death, we could find out more about Ami and her past and their relationship could evolve further.
Good job and looking forward for more content from you.
