The juiciness of the ball is so much fun! Love how silly it is that it can duck hahaha.
The only thing I can criticize is the lack of music. It would have made the experience so much more fun.
I do, however, really like the levels! It wasn't just a mindless up-or-down auto scroller. The different paths made me think and kept me on my toes! I also really like how the designer understood the flow of key presses and changed the rhythm to throw me off. Great stuff!
