Thank you for feedback! If I decide to continue working on this project I will definitely use your ideas!Also, could you describe more the ending bug? Are you saying that ending triggered even whithout 10th level?
Yeah, I was level 9 when I found the cracks at the bottom of the cave, and the game let me pass anyway.
I don't remember if I had enough crystals with me at the time though to reach level 10.
Now it should be working properly. It turns out that the trigger for the ending was too big. whoops :P
