Fun game. I don't think it used the theme at all, but it was fun. Of course I've played a million break out games, so this isn't something new, but it was a good remake of a classic game. The graphics were good, especially if you did them yourself! The sounds were OK, but I think they could have been expanded upon. Audible cues when your paddle changes would have been great! Especially when the paddle would change back to normal. If you're watching the ball with the big paddle, when it shrinks back to the small size, an audible cue would give the player an indication that the paddle is now normal size without having to look down to see. Another thing that would have been nice would be to know what the power ups do. So maybe some text like "Big Paddle Power Up!" or something. I think text would make it easier for the player to then associate the power up symbol with the functionality. I would have also liked to see power downs. In breakout you get power ups, but some times you get power downs. So you have to be careful to only grab the good ones in the harder levels. I would also like to have seen several levels. I think each level should be a bit faster and harder allowing the player to progress and really be challenged. I couldn't really tell if the second level was harder than the first. If you wanted to spiff this up a bit, you could also add an online leaderboard. That would have been cool to see my name on there and then check back in a month and see if anyone beat my score.
Anyway, it was a very solid working game. You should be proud!
