As you can probably tell from the style of the summer game, Valve has been kind of obsessed with a few clicker games that have become popular. It started a while ago with Cookie Clicker, then with AdVenture Capitalist and more recently with Clicker Heroes. The Monster Summer Game is a bit of an homage to those clicker games as well as old pixel artwork from generations of past favorites.

With the Monster Summer Game, we're also trying to take the opportunity to highlight as many of the great titles available on Steam as we can. One of the ways we're doing this is by utilizing the Steam Emoticons provided by a few titles and using them as ability icons within the Monster Summer Game. If you're interested in learning more about the games behind these icons, check out the list here.
