Hi, technical developer here. No, saves won’t be compatible. We’re changing the game engine from Ren’Py to Godot, and converting saves is not possible.
Ren’Py is indeed a very capable VN engine. However it suffers a little bit from performance and resource consumption issues, especially on low-end hardware. We hope the Godot transition will allow us to alleviate those issues, and allow more players to enjoy the game. It would also allow us to offer more features to the game in the long run. Saves cannot be converted due to major differences in the technologies used in the two engines: Ren’Py uses python, with the use of pickle for data storage, and Godot uses C++, with a custom data storage format.
