So very, very nearly there! Finished A (and killed a Mummy at the end), then moved onto B, which was a bit of a boss-a-thon in the end, with some bats, Death (it seems the other Death wasn’t Death at all), and a big blue gargoyle thing.
And then, Dracula! Thankfully, at this stage in the game you can continue from just before each boss, so I don’t have to go far back each time I run out of lives. Which I did. A lot. I can’t even get rid of more than half his energy. Rubbish.
