I am glad you enjoy the game! Right now, I am trying to finish the game. The main story is finished, and I am trying to complete some of the side content. We won't be seeing new transformations in the game at this point, since I am focusing on the final steps.
After this game, I'll work on another one (I have already started working on it, although progress is slow while Caliross is still the main focus). It's a sequel to a previous game of mine, and it will use Ren'py.
