Vampire Revenge is an adult 2D game.
This was my first H game and has its quirks, mainly a quite outdated user interface making it a bit annoying to play. But as my first H game, I think the concept was quite innovative in the field.
Where to get it ?
The game can be purchased on DLSite or you can get the download link by becoming a patron.
The game also has its own website and you can check my Patreon post about it for more info.
