Glad you enjoyed. The family drama is intentionally left somewhat ambigious, and some details are scattered across endings.
My goal with Lily was to make her subtly lonely but very likeable, but maybe I neglected how socially weird someone in her situation would be. Having her be that way while also following the player around and talking to them is a tough balance.
Sorry about that error, it only happens the first time you launch the game, then it fixes itself the second time. You can use the most recent autosave and it will put you close to the end, then it'll work. And now the latest version doesn't have that issue anymore, thanks for the report!
I wonder how it slipped by this long, maybe nobody played it in one sitting? Who knows.
