If you just play this game, you will encounter a few bugs and 'in development' dialogue at the beginning and in some places it will be painfully visible, that there was meant to be more there, but that's it.
After completing all endings, getting every scene (including one where I needed to edit the script file) I can say that 'finished ' describes this game only if interpreted as 'you can get to all (sort of) endings and dev stopped developing it'.
