I've been playing StarSavior for the last couple of days, and the early impression is great. I haven't explored everything yet, but it has fairly unique gameplay, impressive visuals, some of the best character designs in this genre, and particularly lively character expressions. Can't comment much about the story yet.
Some people have reported performance issues, but it runs smoothly on a 2-year-old midrange phone and a 9-year-old PC.
I'm surprised it didn't become more popular during its initial release in Japan and Korea.
