Very interesting and fun concept! There were some elements not immediately clear to me at first. For instance, I didn't realise I could fire the ball into a wall and catch it again. I also encountered some small bugs, which you might already be aware of (totally acceptable for a game jam!). The second-level tutorial UI stayed on screen and made it hard to see what was going on, and I could get a free score by moving an obstacle into the goal post while placing it. These didn't detract from the overall experience, just wanted to share for visibility. Really unique and fun. Nice work.
