So going through the three websites I want to release the PC version on...

Gog: I may have a shot, but the release there will likely be after the others.

Dlsite: I just registered my circle, so now waiting for approval. Unlikely that those located in America will buy from there as I'll raise the price to ensure I get a decent income from it. (Still less than the average price of DLsite games, though)

itch.io: This will be the primary release location and the ONLY location you can take advantage of the "Free For Two Days" deal. So if you want the game but are strapped for cash, this will be your best bet. I only ask that you spread the word if you're getting it for free. (I'd like the word to be spread either way, but this way I'll get more hits)

As for Google Play, I don't know if the release will be as soon. There's compatibility issues with the achievements system. I have one more theory I'd like to try and if that doesn't work, I'm waiting on a reply from a person who does Ren'py tutorials on tumblr.

Either way, itch.io is the best bet to get the PC version of the game, free or not.
