It's a coloring book page where you click on frogs until you run out of frogs. It's perfect at doing one thing and that's praise. If you like it, the same dev has dozens of these titles with different hidden objects, all across the steam store.
There are 100 hidden frogs and you've got to find 'em. I beat it in less than 10 minutes, but since it's free, this would probably make a fun game if you're babysitting a 4 year old or something.
