1: The Non-paid version is a public demo of the game to let you play the game for free to see if you like it and want to buy it on itch as an early access game or support us on Patreon to help our development of the game.
The demo is a fully released demo features all of the character routes in the game up to their routelocks.
The game does not have a launcher client so it does not update through the game. When it is updated you have to download the latest version of the game on here or on our Patreon or Subscribestar.
2: Yes, Aeon does have more events in the paid version of the game. Though at this time no romance.
3: Nathan at this time does not have any additional events in the latest version of the game. He does not have a phone contact since we do not have any personal texting events with him currently.
4: Right now in the paid version of the game the writing for the Bakery is complete and you can reach the end of the Bakery route, however, CG Scenes are still being made for it. We are now working on writing the events for Kate's route past her routelock and as we finish the routes in the game we have a poll on our Patreon to decide which route gets completed next.
So as for hours depending on your reading speed could be around 1 - 2 hours of extra content currently.
Thank you for your interest in our game. I really hope you've enjoyed everything the game has so far.
