I'm glad you liked the game. ^U^
You did not repeat any other idea put in this forum.
I think the idea of being able to acquire the amulets in the Temple seems good to me, and I had already thought about adding the healing of life with Dr. Nora.
The change of character unfortunately I can not do it because it involves drawing much more. (Already with what I have to draw I have for years of content. XP)
And as for the other 2 ideas, they will be developed throughout the plot, in fact more details will be explained in the next update. ;)
