Bit missleading. So i will clarify. Bit of context first, Author of Dog Princess said they wouldn't post updates untill LL project is finished, sometimes within this year, after 6 months no dice so here's the reasons.
The main author of LL is the artist, DogPrinces Dev is just the programmer of that project, issue said main author has had "a happy turning point in his life which has them extremely bussy"(prolly a parent now lmao). So that project hasn't been going smoothly and issues in its development cycle will continue, it might get banked.
DogPrincess however was started as a passion project, the reason it was also a flash game was direct inspiration from LL, but the dev figured out they could do more with Unity and thus started developing the 2.0 game. Many people showed interest in Dog princess project so he got 3 new people into the project. Originally it was so he could get more time to finish LL, but since that doesn't seem like it will happen any time soon and 2.0 Dog princess has many new features the Main dev will just continue working on DogPrincess.
Final note:In theory this hints at LL project being abandoned by the dev but its not exactly stated, maybe they haven't decided yet. Also it implies that DogPrincess will get a huge boost in development regardless of how LL continues, that said the update is mostly to clarify about the LL project, on the next update we should get an aswer
