Sorry for the late reply. I took a look at your Patreon, but I don't see Steam keys mentioned anywhere specifically.
Only the description of Tier 3 for $10, True Gamer, alludes to something like that: " Digital Downloads of Flambeau, Lewdware, Marble Maid, future Shady Corner games & DLC"
Could you clarify what the conditions are to get a Steam key? Does one have to be a supporter for more than one month?
Thank you.
