I'm feeling really flattered that you took the time to try to piece together some sort of narrative, but I've already stated on the game page that there's no story in the demo yet. I don't want to spoil the story while the gameplay foundation is still in active development, because it can only be experienced once.
The current "mystery" in the demo is just there as an off-beat mechanics showcase right now.
Dialogue system was only just implemented. There will be options later on.
If you're really that interested in a story then stay tuned - it's already fully written but it won't see the light of day until I am satisfied with the mechanics.
