As a love letter to Bloodborne? It's pretty good. You could tell they had a lot of good ideas going into this, and the original content they added in is pretty solid too. As a video game? Also pretty fun. Doesn't overstay it's welcome and, if you're familiar with Bloodborne on PS4, you can get into the swing of things fairly quickly. Makes for an enjoyable afternoon, and I think that's pretty good for being $Free.99.
