Simple yet neat!
I think this level was already fairly difficult haha, I feel like the game was a bit harsh on when you were hit, I think it'd be nice to have the hitbox of the player be a biiiiit smaller than the actual sprite for some leeway
The 'guards' and the player being a ball also made me think of pinball, like flippers and, well, the pinball! Maybe inspiration for a spin on the mechanic you've got now? (...yeah that sounds a bit too silly)
