I really like the artstyle, and the animation's chopiness honestly kind of adds to it. It feels cool and kind of old-school. Like it's from 2008 or something like that. Don't know why, it just has that vibe. It's very detailed, which I like. That cigar flick was also pretty fluid. I'm invested in the story, too, and it's interesting how you decided to break it up into small pieces. Maybe you should try to make them a bit longer/merge every few into one so you don't end up spamming the portal though.
