Werewolves are one of those things that haven't been seen too much in games, as they've been shunned in favor of zombies and ninjas. So, seeing Blood of the Werewolf, a 2D platformer where you play a werewolf, on Steam is kind of a novelty. According to some screenshots, it appears to have sections where you actually are a werewolf, and the less interesting non-werewolf sections. So, it's not exactly defined whether or not you have free will to transform into a wolf-like state. Currently it's 20% off its $9.99/£6.99 base price on Steam, so if you want it, now might not be a bad time. Check out more at its Steam page.
