Hi, thanks for playing and commenting! It's great to get your feedback on these things. I definitely need to make a screen for showing what all the powerups do (w\either a standalone screen, or something at the beginning of a level explaining the newly-unlocked powerups, or both). And yes, I definitely need to tweak that ball launch--that one threw me off too as I played, and was just one of those things I didn't get to tweaking before I ran out of time.
Thanks again!
