Thank you!
Unfortunately, we did not have time to add the item descriptions to the game itself, which is why they are listed in the description. And I completely agree with the poor mixing criticism. We would have definitely tried to tackle this if we had more time.
I don't understand your criticism of shooting though. You're only supposed to throw a ball at the start of a level and after you lose a life. That's what Arkanoid and Breakout do, which this game is heavily inspired by.
