I know you mention this is more of a proof of concept than a completed game, so I wanted to make sure I pointed out a few things to help you improve for the next version:
- when you get the room key from the tub, it's missing a self-switch, so you can get unlimited keys.
- if you go right in the hallway after coming out of your room, you can enter the middle door in the next section... and still continue to obtain room keys from the tub in there. and then when you exit, you leave from the original room, not the new one.
- I have to say, the footstep sounds started to get on my nerves after a few minutes.
- Sometimes when changing facial expressions with your busts, their portrait shifts / moves and it kinda made my brain think my eyes were playing tricks on me.
- Some of the keys are KEY items, some are not (room 2 key that I got from Gerald, for example)
I think your art direction is really unique and the music you've chosen is lovely (I found the bar music to be especially fitting). I'd be interested to see where you take this beyond the prototype stage -- good luck making improvements and getting closer to complete!
