I started hearing about that game right after I released Awakening a couple of years ago, and I had never heard of it until then. Before my game was a game, it was originally a webcomic I did back in 2010. I put it on hiatus in late 2018 and decided to try making a game based off of it instead.
In this case, it is a coincidence. Same name, different game, lol.
Prob would be best to rename it because Crystal Story has been out for ages. That's like the Tom Clancy: Outbreak (right when COVID hits) and or Immortals Fenyx Rising (originally known as Gods and Monsters).
I'm not saying your idea is bad, but it would help if you talk to the original creator and bounce back some ideas or just come up with a new name so it doesn't reflect like it's an origin story.
Edit: Anyway it's your game, your dream, do whatever you think is best and i'll be there to support/play at the end!
