I originally rated this game a lower score because it was a bit buggy, and crashed often. There is also a 'space invader' element in the game which is very difficult to pass especially if you're on mobile and have mobility issues. I was able to finally pass this stage, and also the game no longer crashed. Ive just finished it. It's a beautiful game, beautiful artwork, beautiful music, and very good creative gameplay and puzzles. Well done to the team who made this.
