To get a key for exclusive content you can visit F95zone and search for my game thread. The access key leaked the other day after the update was released.
You can also wait for version 1.0.2 because everything that is exclusive content in the current version will be unlocked in the next version.
You can also support me on Patreon or subscribestar for $5 and legally get the key on Discord...
Three options and three possibilities and the choice is up to you. It's a free world and nobody will convince you to do anything. Thank you for your interest in Doghouse!
