This sucks. Not for us, the players. But for the great developers like yourself. I really loved the bussiness model that was here, and now sadly. It is gone.
I already owned TTUV on steam, but not SL.. And ofc, i bought it straight away.. Not even fully so i owned the full edition again, but also to support you where i can.
Speaking of Steam, (and i know this doesnt work for everyone..sadly) maybe you can go fully to steam and patreon? I play Come Home there, another AVN, wich is Free to play, but she also uploaded a Premium Edition wich will get the patch earlier then the F2Players..It is basicly the model you have here..
I dunno.. I wish you best of luck..and i keep playing the games, as long as i can.. and i try to support you with the budget i have.
This suck. Period
