Thank you for the constructive criticism! You're absolutely right that an attack animation would better communicate to the player what exactly happened. I think a lot of improvements can be made generally I'm the art department. Specifically with player interactables.
We're planning two update cycles and hope you'll give the updates a try. They will include new mechanics and features that I believe will address your thoughts.
My co-creator, Nixter, made the music. Funny enough, he made the track after I had done the wizard animation so he'll have to say whether or not that beat was intentional!
