Vampire Survivors : The other game I've been playing where you die over and over but this one's 1/20 the price of the other

Vampire Survivor is a rogue-lite ... wait come back it's good ... if you like that sort of thing.
It sort of came out of nowhere and went from a little known extremely cheap game (think it's $2.50 at the moment) to being all over the blogosphere the youtubs the twitchers and tictacs
On the surface a very simple game you control a vampire survivor through a series of environments with their own set of enemies bosses and environmental pecularities and just have to survive collecting power ups by gathering the gems enemies drop.
