As a huge Castlevania fan I must say this is choice.
The controls are smooth, and the level design is great.
I beat the first level and boss on my first try, but had to exit, and had forgotten the password so I had to spend an hour trying to beat it again because my fingers magically transformed into dicks or something. I also see the passwords are right there in the description. Well.
I spent another hour trying to get to that secret fucking boss. I kept dying while jumping over the platforms above the water, I don't know if it was poorly designed or I just suck. But additionally it took another fucking hour of going back there until I could finally beat the fucker. And I could only get that extra life (the one where the garbage can chick kicks you up to it) like once every ten tries. So I just died more often than not. Little things like that took away from the experience a lot.
BUT. Overall this game is too good to let little things like that put me off. So five stars to you. I loved the default difficulty, I thought it was perfect. Though I thought casual was far too much of a drop in difficulty. But that's just my opinion. Anyway thanks for making this game and allowing me to fulfill my lifelong desire of beating up disabled girls with a scarf.
