If you bought the Game on this page you have a download button at the top. The "Claim Steam Key" option is right below the downloads of the game.
If you buy the game on this page, you get a steamkey aswell as the gamedownloads. You simply can activate the key on Steam, even if the game is restricted in your country. Thats how it worked for me.
Is an "overflowing" feature planned?
Like if I pump a kobold full of cum and it reaches the maximum capacity, the cum will flow out of the mouth or nose.
I think it would fit in the game :)
