I had a rough time with the game. It felt like the controls felt too unresponsive. Like trying to go left or right was too slow to respond and would tip you over to easy. Trying to move was also difficult. I would usually Not in a fun jump king kind of way.
Having an explanation that it would be game over if the king touches anything would also help. I was confused the first few times I died.
I like the idea. It's good and I think if i could turn faster/more responsive, I would have a better time.
Good work!
