Hello there! I'm so, so happy you enjoyed the game! Thank you for playing ❤️
The 5 routes are about the DC's personality + their relationship with Mathias: Seeker route, Destroyer route, Ruler route + friendship route + romance route (5 in total)
All the other questions will be answered with details in the next game ^^ but yeah, Filtchen and Yvana ran away, and the plot with Denraxale is a bit "foggy" on purpose, hehe.
Also, please refer to Denraxale using "they/them" because they're non-binary.
hugs,
Ligia
