I played the prototype and struggled with wrapping my head around the mechanics, and I'm still struggling with it, so maybe this ultimately isn't a game for me, but that's okay. I do really appreciate that you added the arrow to the ball so you can see exactly what direction it's going to go in. I also like the drawing the ball back in mechanic, it helps setting up the shots feel more strategic.
I found the bird-type enemy really frustrating and never did figure out how to actually deal damage to it, so that's about where I stopped.
However, the fundamentals are solid, it's got good feedback on the ball (although dealing / taking damage could potentially use some feedback as well), and with a bit of polish could be ready for release. Good job!
