Totally fine! It's normal that not everyone will like a game. You have to keep watch your stamina bar (yellow bar at the bottom of the screen) because attacks consume stamina. Deplete that and you'll have to wait until it fills up enough. Dashing also consumes stamina.
However the part about not being able to move even though your character has already finished playing their hurt animation is a bug, and I've been trying to fix that for a long time.
