Thank you for very constructive and informative comment! I have to admit that the story was started far simpler then this and the idea of the time-loop came with the idea that I want player to experience every endings in the game without reloading save. And since it's become the core of both back story and its flow.
The environment was the first thing I've done in this project. And the few first days of the jam was me creating interaction on the set objects. And I improvise the first draft of my script / story around the environment. It's very fun but yet unconventional/maybe not a good way to make a VN. That might be the reason why the room has so much attention while the writing itself could use more than a few time editing and rewrite ^ ^' (which I'm still keep improving)
I do have fun making this project and really want to do more loop timeline story like this with recurring characters from this one.
And hopefully after the final patch to the game I can arrange time for that to happen. Wish me luck!
