Very interesting idea. The mix of puzzle, physics and dungeon aesthetic works very well together.
What I enjoyed the most was watching my solution unfold after I carefully placed all spinners. That moment is super satisfying. You should definitely explore that more.
I agree with others that the controls were not that great. At times, it was hard to pick the spinners, and the pink mark doesn't suit well. I would change it to an arrow, so you know roughly the direction the missile will be launched.
I would add a missile whistle sound to the missile while traveling. Kind of like this one: https://elements.envato.com/bomb-whistle-BCMB8U6
