My physical copy of Castlevania Dominus Collection is here. I've been meaning to replay Portrait of Ruin, but I feel a little burnt out on Metroidvanias so that will wait until a later date.

I did try Haunted Castle Revisited. It's a short but solid Castlevania experience. It's not too hard either. With plenty of extra lives earned I managed to clear without any continues on my second attempt. It's a neat bonus.
