yep i had this too!
nb Nox sprite doesn't show up properly, because the files in the blushsm folder are a bit messed up and should be renamed for the sprite to go through the animation properly. "blushsmopen.png" should be "blushsmaopen.png" and "blushamahalf.png" should be "blushsmahalf.png".
The more pressing bug i think is an issue in syntax that makes it so the game doesn't track any of the stats. I don't think there is currently a way to get any ending except the bad one. All the "=+" sequences in the script should be corrected to "+=". The first one sets the stat to a number, the latter adds to it.
It is a really good game though i hope they fix it soon!
