The video is impressing.
The demo is too dark in my opinion.
The art is a bit exaggerated.
Try to use more understatement.
The story is a very common theme, therefor you should look for an author who can tell a unique story with details that tell an individual fate.

By the way, ask a native English speaking person to write the drawn text.

I guess that you are lonely wolf developer, but you should collaborate, and I think because of your skills you will find some who are willing to work with you.
Probably, the biggest barrier is the language.
Keep up your work, it looks really promising!

BTW, Pantharay refers to "pantha rei" = "everything flows" of Heraklit?
