From the developer:
Squish is a little game in which you have to squish bugs to earn points, but don't squish the ladybugs. You have to reach 200 points to get to the bonus round. Earning a high score takes a steady hand, quick reflexes, and a strong stomach. Features include wiggly legs, slimy green bug guts, and crunchy, squishing sound effects.
