Hi! I'm happy to hear that you enjoyed playing what's in the game so far, and took the time to leave us feedback.
I believe that when you mention the scene with a much different tone compared to the rest of the story you mean the one with Klaus - that's meant to be a sort of an easter egg and I plan to make it harder to get in one of the future builds.
You're right about the music in the bus scene, thank you about that! I added a second track there to change things up a bit. I would like to have more tracks in the vn, but I need to split my time between writing, managing the whole project and recording music for it, so I'm composing just a handful of tracks per update.
About the amount of routes, I'm taking this project very seriously and I'm aware of the scope. It will take a long time to complete, but I'm committed to finishing it (especially as it pays my bills currently!).
