Good start of an idea and charming, but I find it impossible to control the character in the way that is expected by the gameplay challenge. I did really try, out of about 25 retries I managed to bounce back anything at all like 5 times, out of which only once did I bounce 4 times and that was my highscore. I would find this very enjoyable if the challenge was reduced, for example if the movement was limited to one dimension only + you had more time to figure out that the projectile is about to fire, I could see myself getting hooked for a while.
