Nice this was with new content right?, well now I'm unsure if I want to redo old content or not before I jumpt into the old chapter, not sure if I can reproduce somet things so well.
I think this is more how me and my head trap themself in such decision making.
edit:
I haven't read it before and assumed I remembered correctly when you said a new challange would be added, I guess next update? i would prefer to play when these feel more complete and I can go somewhere with the transformations.
