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)

The mechanic works nicely, but maybe the game would benefit from a twist/addition to the mechanic. Maybe the 'guards' can move around or respond to sudden movements/noise etc. The playable environment could also benefit a lot from thematical elements like prison bars etc. to pull the player in more. These could potentially aid or hinder the player as well. But it works and feels great, so a good start! :)
