This is a nice concept! However, I feel that the red walls go against it. First, it took me a while to understand that I could not touch them (the feedback is not really clear, I thought there was a timer or something). But mostly, it prevents the player to use the most fun aspects of the game: the ball inertia, and bouncing on walls! Instead, the game ask the player to move slowly and carefully, and to stop at every obstacle. This makes the experience quite frustrating and laborious. Also, one of the toughest obstacle in placed really early in the game (a blue block tightly positioned between two red walls, blocking the access of a door), I couldn't pass it (I relaunched the game to explore other areas though).
But once again the chore mechanics has a lot of potential! It sometimes felt great to use walls to compensate for a used direction, and trying to make smooth moves with the ball. Maybe the level-design could be arranged in a way to encourage speed and taking risk?
