You have a great start in your journey in creating and writing games. I really liked the story but would have really enjoyed our main characters how they met instead of already together and would have liked to know how the stone monster came to be and how they fell in love. :)
Also, there were some parts that seemed to drag on and could have been more to the point. But otherwise, you have a great imagination and are really talented I wish you much success in your endeavors in life and hope to see more from your creativity. Here is my playthrough as you can see, I love to laugh and have fun in my playthroughs. I can't wait to play part 2!
