"

If you're logged in and the purchase is linked to your account, you should be seeing a "You own this game" header on the game's page: http://imgur.com/a/wnmSA — clicking the 'Download' button takes you to your unique download URL, which contains a 'Claim steam key' button.

If the purchase wasn't linked to an account, you can make itch.io send you all purchases associated with an e-mail by filling out the 'Recover purchases' form on this page: https://itch.io/support
