This is such a unique take on the theme! I love the callback to Zoetrope-style animation. You can go far if you keep developing this concept. At first, I found the boss HP a bit on the chunky side, but the charged attack dealt significant damage. Some damage balancing might help; consider how many hits a boss should take before being defeated, multiply that by the player’s base attack damage, and fine-tune from there. I hope to see more from you guys in the future!
