How can you rate if the app doesnt work?

Download was fine, met all of the requirements that werent spelled in an Asian language, launched the app...and a button pops up with Asian script and the app crashes.
I decided to try it out after seeing the cinematic trailer on Youtube (knowing that the cinematic was NOT what was going to be offered in the app) but how can you give something a good review if it refuses to be reviewed? The only review I can give is what I was able to experience which was the app crashing. 1 star.
