I recently purchased being a Dik season 2 after getting 80% of the way through season 1 and the game is really funny to play, I can best summerise it by calling it American pie the game.

After really enjoying most of season 1 I decided to purchase season 2, the issue being is there is a glitch with the current download, I paid for part 2 and the file size is correct for part 2 but the issue is when you download the gog app only registers season1 and there is no option to play season 2.
I have reported the issue to GOG support but as it's Easter weekend im sure it will take a few days to investigate and correct the issue.

If you wish to buy being a Dik season 2 please hold off or you will be disappointed as you will not be able to play.
If anyone else has ran into this problem or has also reported it please post any information you have regarding the issue.

Kind regards

If you're looking for a separate entry in GOG Galaxy, you won't find one. Season 2 is actually DLC for Season 1. Launch the game as usual and check the in-game menus for a way to start Season 2. If there doesn't appear to be one, in GOG Galaxy, click the "More" button next to Play, then choose Manage Installation, then Configure. You can double-check that the DLC is installed there. You can also check the "More" button for an Additional Executables menu that would allow you to launch Season 2 directly.

If you're not actually using GOG Galaxy, then check your Start Menu folder for a Season 2 shortcut. If there isn't one, search the game's installation folder for all executables.

Especially if it's a Renpy product (which i will assume it is).

If you look at some of the VN's out there, they might have a demo, then the full version it's a replacement of a few pyo files and including a few more directories (or if it's packed, a rpa file). Some VN's that are 'in progress' have 'chapters' where it may include all previous chapters as well, though you're likely re-downloading the entire thing again.

The biggest reason to do it in this fashion though, is to either a) use less space as sprites/images are reused, or b) if you made any decisions that are part of a path to unlock different parts of the story, much like 'choose your own adventure' paperback books i read once when i was a kid.
