It's a shame it's currently unfinished - you've got a very neat interaction system in here.
Giving the characters a drink to talk to them, and to ask them certain subjects... I like the concept too, and the little hint of the "heaven or hell" drink for the end sounds very intriguing.
The 3D enviroment with 2D character look is also interesting, and them having that "paper cutout" aesthetic with the wide border is neat. The camera zoom during dialogue is also pretty neat for centering the shot on them.
Not sure how much you can do in this version, I just tried giving drinks until I got stuck, so I'm not sure if I couldn't find interactions or not. The dialogues present here are pretty good, with each character having their distinction in both looks and speech. It's a very promising little game!
One thing to notice - the transition between dialogue and player controls doesn't hide the mouse cursor all the time.
It would be cool to see a complete version of this! Great entry nonetheless.
