Thanks very much for your comment. English is not my mother tongue and this was quite a big project to tackle alone, so AI really helped me get it finished. Mind you, I did edit a lot of the text to make the story consistent. The same goes for the art. It took me quite some effort to develop a consistent style across the game. :)
Regarding the creativity, I think the main thing is how you develop your mystery and the way you design the hints to provide an enjoyable experience for the player. In the end, that's what mattered to me: to provide a game I would enjoy playing myself (if I didn't know the solution already). :)
