It's officially May, which means a new bundle of free PC games is available for Twitch and Amazon Prime members. This month's offerings include a number of widely respected indie games. To find your freebies, just click the crown-shaped Prime Loot icon next to the search bar on Twitch. That opens a drop-down menu that contains your free games. [Update: The end of the month is in sight, making this your last opportunity to claim these freebies while they're still available. Doing so will allow you to continue playing them even after they're no longer offered for free.]

One of the biggest games this month is the mind-bending 3D platformer Psychonauts, in which you enter people's minds and explore physical manifestations of their psyches. Gone Home is a first-person story-driven game. The adventure game I, Hope covers some heavy subject matter, and for those looking for fast-paced action, High Hell is a first-person shooter that encourages speedrunning.
