This is an old game made by Anthony Lopes. This game is what inspired me to make Bug Takeout. It's 4-player coop against egg sacks and alien bugs that try to acid spit you to death. You'll notice I've taken off Bug Takeout from my website recently...

*whisper "And I've started the commercial production of a game. Codename "Critters". I wonder what it could be?

I came across this game while looking for a free platform adventure game. This one impressed me with it's simple mechanics and open world aspect. There are several islands to explore and some locked doors and hidden areas. The game makes you figure out how to get to them and even though you can follow a simple story, it doesn't feel linear. Give it a try.
