Just finished playing through the game, received "Good ending one" and one ending simply stated "The End", also got one preliminary bad ending even before Chapter one by listening to my silly parents and one bad ending in Chapter 5 when trying to hit the guard with the lightning instead of sleep spell. Hmm, seems like there's one more good ending at very least and probably one more bad one?
And I didn't unlock everything in the gallery yet. But really loved the story and the dragon was cute, the game's not long, took me maybe 1,5 hours to complete.
