I currently played the 2.1 version so i have no idea if what i found still applies to the current version
The animated scenes were indeed affected by the compression
There's also a scaling issue
You can confuse the game as well, by pressing in the heart instead of the house, clicking on Neko-chan and pressing the skip button
You can soft-lock yourself from meeting Lorica by skipping after any scene after the first neko-chan's one since Ren'py takes it's own choices and the story frecuently places the MC as a relative nobody that everyone is slowly getting to know to someone they knew all their lives.
And on a lighter note, MC reminds me of Lios from Cosmic Break, doesn't help that Lios is blonde as well
