Well, I enjoyed it a lot
I really liked your earlier work "Bad Idea" and the same goes for this as well. What I mostly enjoyed about this was your drawing and animation style. Also the voice acting was pretty nice as well.
However what I didn't like about it was the shift of tone in the story. When the phone was rejected, I gave it sympthay and that was starting to set how what I expected of the rest of it. Suicide? Revenge? I wanted to know. However, the following scene kinda messed up things. The music ruined it. The sound of the music was fine, but the lyrics simply and bluntly killed the mood. Things like that, and a few cartoony scenes.
Maybe I was expecting something serious? I guess so. However, I did enjoy it and can't wait for me.
