Pesticide is an action/tower defence type of game. Play as a giant insect monster and try to protect the queen from an endless wave of determined attackers. Place other creatures around the path to help kill the enemies.
Eat enemies that are small enough to get bigger and stronger, or kill them to get resources used to buy and upgrade stuff or heal the queen.
Read the readme file for the controls.
