If this page doesn't display properly for you, you may want to download the program and try running it from your hard drive:

• critters.jar (an executable archive of our solution; download and double-click it to run it)
• critters.bat (Windows bat file; try downloading and running this if you aren't able to just double-click on the .jar file)

Or if you know how to use a terminal window, you can run the program from a terminal by downloading the .jar file and then typing:

java -jar critters.jar
