Okay I played the 0.2 version I think, which instantly made me fall in love with the concept. Knowing it was still under development, I felt a crunch in my heart for having to wait till it's finished. I came back to your page here to check out how far the game has been progressing (and a little hope that maybe it's finished) :'D
But, here we are.
I immediately jumped to your page and saw your other game, Once in a Lifetime. Boy, oh boy was I excited. Played it all night long and more, I think I finished it in a span of 3-4 days just because I was savouring all the sPiCe and pLoTs. Amazing story, amazing concept. Great job, Caribdis. XD
In any case, sadly I don't use Patreon nor Paypal as I live in a third world country which makes those option kind of hard for me to do, however much I want to donate or help you making the game. I hope you can consider releasing this game (or your previous one) in Steam. I will wait patiently, knowing that you will reward it with another wonder of a game. ;]
TLDR, you are a ray of sunshine in adult games and I am a fan of your work. Hope you can finish Eternum soon and somehow release it on Steam!
Good luck~
