It's like the original Kid Dracula but good, except that the first already was really good.
A bit difficult at parts, though I think using save states (but only at checkpoints, so it's like infinite lives) makes it much more fun.
Unfortunately the difficulty's increase towards the end feels mostly unfair (another point in favour of save states here), and there's a lot of platforming traps you can be fated into before you even see them, but it's still one of the greatest games out there.
