As you may know, Caïssa Board was developed using the Unity game engine. Recently, Unity has updated its terms of use in unacceptable terms, which led me to change the game engine. So I began the transition to Unreal Engine.
Since then, the conditions of use have improved, but I realized that Caïssa Board would benefit greatly from a switch to Unreal Engine. Indeed, I noticed that the camera was fluid and that the user interface navigation system was efficient.
As a result, I decided not to go back to Unity. In practice, I'm going to have a lot of work to do, but I'm not starting from scratch. The algorithms are done, the models and textures are the same and I simply have to transpose what was done on Unity to Unreal, while if possible improving it. Some special effects are specific to Unity and will be difficult to reproduce on Unreal Engine, but this won't have any major consequences.
I apologize for the extra delay, but I feel that I have made the best choice for Caissa Board.
