It will be some time before the story and game will be finished as this is a single person project and I am quite busy at the moment but i am glad you enjoyed it. The continuation will be added hopefully by next month.
With regard to the walkthrough, it will be added as soon as possible as there 3 different difficulty for the game. I understand that many players find the puzzles a bit hard though I'm glad to know that it is still possible to be solved without a guide.
