This is a simple little tech demo I threw together while working on Rat Race. There was a minigame where you had to lure cockroaches and the lead engineer said it would be very difficult to have a realistic swarm of roaches. I created this demo over the weekend. Unfortunately, we never ended up using it in the game.
If you want to check it out, download it and click anywhere on the screen. The roaches will swarm that area.
