Picking up the king and using it to kill enemies is a creative interpretation of the theme.
I found the controls to be a bit wonky, I'd often bounce around when colliding with walls which let to a lot of situation where I had a harder time going where I wanted than I should have.
The music seemed to reset a bunch in awkward ways as I traversed through the world. Sadly means I couldn't exactly listen to the music in full as intended.
I made it through to the third king and kind of stopped paying attention and died, since the second king had a different color I was curious on if there was any specific end or milestone or if it truly is just an infinitely long game?
