What I liked about Risk of Rain- the retro look, the innovation it had at the time, the music, Providence, and of course, HAN-D.
What I liked about Risk of Rain 2- The music, the items appearing on your character, and all the little secrets and nods to the original game put into the descriptions.
But most of all, I love Hopoo Studios the most, they're a great set of people to look up to.
