Wow, epic fail by me, when I was testing I couldn't figure out how to shoot the balls hard enough... Now I realized you hold it down... lol
So you didn't mention this to the dev or other testers? Sounds like you came across a problem and ignored it/gave up. Great testing there.
I keep watching the video over and over. I really want to try this out. This is angry bird-esque looking but looks to have more strategy than luck.
