Caribdis, the only thing I can say is Bravo. This is a masterful work.
You have done something absolutely amazing with this project: making a funny and dramatic sex game and bringing it to completion. It's made me cry a little, laugh many times, and orgasm many many more. And you've left it online as a pay-as-you-will game.
You will be the first developer that's gotten me to pay for a porn game. I am not in a place where I can support on patreon at the moment, but I will absolutely tip my hat and my wallet to this amazing performance.
Best of luck with your ongoing endeavers with Eternum. I will follow your work with great interest. (As soon as I finish my second runthrough of this game)
PS and easter egg spoilers: Could you please confirm that the flamboyant fun-loving man we are introduced to in Japan is Linus (sexy tech tips) Sebastion or a parody of him? That was the best easter egg/reference that I've found in the game, and made me actually laugh out loud for about 5 minutes.
