Thank you for bringing the VN world to the VR space. The dialogue system you've been working on seems to be shaping up nicely. I saw someone mention that you could just tie the progression of dialogue forward to a button instead of a Ray interaction, which isn't a terrible idea! Maybe even offer both options and leave it up to the user.
I do think this could have benefited from some interactive components in each scene. I know the focus in VN is the story and dialogue, but why limit yourself when you're working in a new medium like VR? Bring the player into the story!
On the technical side of things, I did notice some rough edges on the characters. Since there isn't a ton of game objects flying around, you could probably turn up the MSAA to the maximum to further smooth out those edges making the game look much more crisp.
For the dialogue system, I am excited to see if you further develop it. It can extend far outside of just VN games. I might suggest having the dialogue follow the user's headset though. Kind of have it float into focus with some interpolation.
Please keep building out the dialogue system! With more polish and work, you'll have a strong asset on your hand to use in games or possibly even sell! Thanks for joining the jam! Hope to see you VN framework in the Halloween Jam!
