Good.Here are a few suggestions!
Ah arkanoid. We have seen it everywhere. It is always fun to see it with new graphics and powerups and a few twists! this one was good, but It could use some fixes.
There are a few glitches in the physics department that should be looked at. The ball sometimes kind of likes to stick to the sides and take out 4 or 5 blocks at a time when you only hit one.
I felt the graphics looked nice. I was thinking it would be kind of cool if the ball glowed a little bit though. Rather than just turning it red, and green, why not give it some lighting?
The sound was the worst part about this game. I disliked the music alot, and I felt the "boing" was kind of odd. The explosions sound like you made the noise with your mouth.
I think that you could add a little bit more flavor to the levels also. I kind of expected the "ACID" boxes to drip acid down, taking boxes with it, and also killing the paddle if you touched it... would have been cool XD.
It was a great game and I would love to see it re made.
