I’m not against this game either! It’s cute and relaxing, and I managed to do some bat art with my friends. It took me less than an hour.
Open Country is all about travelling around and making new friends. There's really no win condition, just the joy of having lots of friends following you, be they fish, turtles or even bats.
You can use the arrowkeys to move around.
If nothing happens, try clicking on the game with you mouse so it can get focused.
