If you mean impossibly difficult (without cheats), then maybe so. I liked that game a while back but now it is just out of hand with where it is going. It seems to just be a style I am not down with. As a fighter it has gone more towards the imbalanced side of things with every update, and as a hentai game it is going more extreme graphically with what is done in game as well. Certainly not my cup of tea with where the game is going.
What is however, and why I think this belongs is that I am in the planning phase of a game (that I would be impossible to implement on my own as I have 0 knowledge of anything that I could potentially use to make said game) that I want to make or have made.
