It's a shame this game wasn't finished with a proper ending because I like the premise and stylistically I think this fits perfectly for SBIG in the vein of the janky Unity walking sims of the 2010's.
I loved all the character art, especially the cursed Unity bean speaking in wingdings and morse code!
And I just loved the environment, the cursed textures, the wildly inconsistently sized props, the sheer number of things laying around, and the little variations between each floor and bedroom was really neat! I would've loved to have played a proper murder mystery in it, as I just love me some largeish detailed levels!
For future work though it should be noted the collision detection on the interactable passengers and environment items is borked. It's possible the interaction raycast is fighting with the players own collider? Either way that's the one thing I think can be fixed and saved for another game if you don't plan to ever finish this.
A part of me hopes it was the vampire girl or the candle.
Good work on submitting what you did finish!
