My honest opinion about the game.
First , congratz to the dev for doing something i didnt see in years , a kind of slowmo fatality on a X game and also the grab and fight system of the game i think it will show alot of potential.
the fighting stuff is great , because think about this , with this game as a blueprint , why not add character movement like RPG , equipment like sword and shield since the game let you bloq allready , then a battle state you enter either in the world map movement or 2D gameplay , it will be fun to play with story or sandbox.
the X related stuff , its just few things , but it shows the potential of doing combat + dynamic scene when you play correctly so its great.
then , i was thinking after seeing the gameplay etc , what about a medieval game with rpg elements , combat , and few more scenes when you win those battles , even more gore stuff like mortal kombat so it mixes fun gameplay and X related stuff.
so 10/10 on the dev for this showcase of something new.
