Hey, thanks for your feedback! Very glad to hear that you enjoyed the game!
Yeah, it was hard to estimate accurately the size of the mansion until very late sunday evening, and even more so in addition to the light&dark mechanic.
We intended to have clear feedbacks with sound design, unfortunately we didn't have time to implement them. And we didn't realise that the player had literaly no other way to know that a new door was opened until it was too late. Clearer mentions that you completed each "phase" of the game would have been very cool. Your idea of directonal sound is very intersting, we will think about it when making a more polished build!
As for the twist ending... yeah, your comment is spot on. We didn't really know how to end the game properly and felt it would be a bit strange to leave it unresolved. The idea was actually present in our mind very early, but we didn't think about how to bring it subtly until we had more or less everything else in the game. Maybe you're right, and mystery would have been better than a half baked end, but still that was the story we wanted to tell so we did it anyway.
Anywayn thank you again for your comment, it's really appreciated!
