Found the controls intuitive which is good. The first few shots felt awkward like the cannon ball just fell out of the cannon but I got used to it quickly.
Inspiration from games like Peggle which I really like. I also like the multiple levels with different challenges. May want to make the ball bouncy to ricochet off of walls and bells
I love the concept of limited jumps and having to collect them to progress. Controls feel smooth but forward velocity could be adjusted but that may just be me.
