Game Jolt is a platform where indie authors can offer their games to the public so they can test them, detect bugs or suggest enhancements. The platform has its own client that allows you not only search, download and install games, but also write reviews and rate those games regarding their graphics, playability, and more.
You can download the client for free from the developer's website. In order to have access to the featured games, you need to create a Game Jolt account, or enter using your Facebook, Twitter or Google+ account. Once you have done that, you can search for games by name, theme or keyword. Each game can have different options. For example, you can download some of them, while others allow you to play them online. As I said earlier, you can post your opinion about a game, as well as suggest any change or improvement. In this sense, the platform is a true game-related social network.
The main disadvantage I found does not have to do with the client itself, but with the games it offers. Some of them are very basic with poor graphics and weak stories. Others can't be played at all. This is understandable, since most of the games presented are from independent authors or small companies. Nevertheless, you may find some hidden gems.
In sum, if you love video games and want to look at what's new in the field, you may want to try this program.
