Fun game! The piranha behavior is super interesting and well-done, especially for a three hour jam. My only criticism is that the music can get a little repetitive, but other than that this is a very interesting take on the theme!

Cool idea with straightforward controls! You may have already thought this but it would be neat if the police had different HP and a scale that matched it. They could start off as big enemies that shrunk as more piranhas attacked them.
