Great game! Really fun concept, liked the last room where you have to seperate from the ball for a while. Pressing Z to throw / catch didn't feel super intuitive to me, but besides that, really enjoyed it! Great job!
I just checked and realized you also have arrow keys working, but by default I was using WASD so having to also hold Z while potentially holding A was a bit hard to do, but it's fine for the arrow key controls.
