Yes, there are eight endings! (One is a short "Bad ending!" at the very beginning)
I really wanted H2 to be easy to understand without playing H1, so thanks a lot for telling me you were okay with it. :) (I mean, I wrote it, so it's hard for me to approach it without preconceptions!)
For the third, though, people will have to play both 1 and 2, but it'll be the last, so, I hope they'll be willing to take that step :D
