Never heard of it, but I enjoyed the videos of the game play that I just watched. I did not expect that much similarity to the Castlevania series, this looks like it's close enough that I'm actually a bit surprised it wasn't sued out of existence unless it was released before Castlevania.

Suppose I should give it a try some day.

I grew up with this game, since we had SEGA consoles, no Nintendos. The later game is a little tough, though. I still really enjoy this game. Just the first levels are a little slow-paced.
