Wow, this is terrible. The art style is clearly made by an amateur and you can clearly see how some of the drawings are 3D while others don't even have shadows. It could be an artistic choice, but I'd say it's a poor one. The writing also needs improvement, the dialogues feel unnatural and the text on screen even has some typos like "hlelo" instead of "hello". Not to mention that one voice actor blindly says the emoticons out loud (I think they were only a place holder to give them the mood they should use to say each line) and the other one doesn't seem to even speak english. These mistakes just shouldn't happen, they're basic stuff.
The music is a cover of a very well known song, but the audio engieneer probably forgot how to use compression so it sounds pretty distorted and hard to follow. It conveys the emotions of the film pretty okay, so I'll let it pass.
One of the things I do like about this movie is the amount of pop culture references, you have bands and meemes and even websites in there to look at and enjoy. Overall nothing too new or interesting but there is a lot of effort put into it. 2/10
