Noice work with the game! I really enjoyed the "flinging myself at everything" xD, the sparkly sound effect is a neat touch x], and ofcourse the adorable rollin animation :]!
I did unfortunately stop a bit early because the gameplay was becoming time-consuming rather than fun over time, I think having the speed go down less so you can destroy more obstacles in one go could be interesting or increasing the bounciness. Maybe even making it so that you can shoot while you're still moving?
All in all, ya created a kewl cute game x]! Great work bud!
