I liked the mechanics, you can easily do a lot of puzzles with them and it's cool to use them. I just feel like it would be interesting if the ball was leaving the whole or if the idea was to Carl to throw the ball first and we having to make the ball go back to hit him, just to explore the concept of "roles reversed" a bit more. I'd also recommend changing the color of that one power up that makes you change the ball's direction, because it was quite hard to see due the low contrast. Interesting entry, nevertheless. Good job.
