 The heart in this project changes sizes when the robot touches it.

Less Comfortable: Program a sprite do something when it senses something.

Comfortable: Program one sprite do something when another sprite touches it.  Program the other sprite to move with arrow keys.

More Cofortable: Program one sprite to get a point (use a variable) when another sprite touches it.  Program the other sprite to move with arrow keys.
