A very nice game and thanks for the Zombie jumpscare!
I did like the cutscenes and the art style you went with for the game. The art so far is consistent and of a good quality.
In my opinion I think the biggest improvement you can make is with the U.I especially the dialogue boxes and text formatting. Once they match the rest of the game's style they will look good. Maybe add a small picture to highlight who is talking, or a different text colour for each character?
As someone else mentioned, I do think more variations on each rooms would look better too.
Overall this is an enjoyable game, its impressive especially as it is an early version as it states in your description.
