Does anyone knows this game?
Name's Nosferatu, a side-scrolling game for the SNES. The concept is basically Prince of Persia meets the aesthetic of Castlevania. I'm an aspiring indie game designer trying to develop a somewhat spiritual successor to it, because even though it was a pretty good game, it had many problems, such as fake difficulty and some strange design choices, such as making the protagonist a guy with a jock jacket who punches and kicks his way through the entire Dracula castle.

My question is: if you could, what would you change in it?
I suggest you download the game and try it out, if you can. I'll wait.
