Hey, tried out the demo, thought it was really cool!
To avoid rambling for too long, I'll just share the thoughts that stood out to me the most ;)
Firstly, I'd like to say that the 3D environment, especially the interior design, is really polished and well made :) Good job!
You guys also did really well when it comes to the movement system. The player character feels a tiny bit slippery, but having him pathfind to wherever you press makes navigating easy and satisfying. It may seem like a no-brainer, but a lot of similar top-down games with the same control-scheme don't have this feature. It's a great addition!
In terms of text, I would strongly recommend you use a standard, readable font. Using wacky fonts for titles, names etc. is fine, but generally, using fonts that deviate too much from the norm makes the text less readable, which can lead to a frustrating player experience. This is especially important when the story and gameplay are heavily text-focused. I would personally use a more standard font for dialogue boxes, descriptions, etc. (But take that as you will)
Anyways, keep up the good work. My biggest take away from the demo is that it feels very inspired. Your enthusiasm for this project really shows :)
