I like breakout and this is implemented well, great colours, nice camera shake and the rare evil ball. But I agree with Kauyon_Kais that the real physics forces on the paddle are problematic, and why I couldn't even complete one level because I could never get the paddle in position, even on really easy rebounds. Quicker acceleration and more friction, I think. And as Andriks advised, use a smaller in-situ screen and let users maximize if necessary, can help people still play it if they're having performance problems with a large size. Assuming a 16:9 ratio, I use 960x540 or 960x660 depending on whether I want to leave the fullscreen button available.
