I've been throwing around designs for the breakout clone. I'm a huge breakout/arkanoid fan, so the ideas are just pouring out. One idea is after a certain time limit an enemy comes onto the screen and tries to eat your ball. Enemy paddles that act as blockers.
My basic gameplan is this:
1) Decide on a format for storing the levels.
2) Create a basic level by hand.
3) Work on physics, paddle movement, game functionality, (basically get the game working).
4) Once the game is working, build a level editor and better graphics for the blocks.
Coding should hopefully start next week.
