So how many acts are you looking for here, and about how many hours of gameplay? I'm curious at what your goals with this in the end are.
There are going to be 2 acts, the second act is still currently being made slowly by myself and before anything is concrete I don't want to set an expectation. There are a lot of ideas that I've gone through and most of them involve changing or fixing act1 a bit and involve using all of the newest elements of the engine including UI, new items, and lighting effects to really make the mood a castlevania/shadowgate type feel to the castle.
While the length of act 2 might be a bit shorter it is going to have some cool things in it. And with it the town should also be finished with more minigames, as well as re-dos of Act1 levels and an in-game UI change. In total both acts might be a 5 hour endeavor, or much longer if you play with a keyboard or struggle with the difficulty
