Katawa Shoujo

Is Rin's end supposed to be hard to get? Because I just got it. By mistake mind you, but sort of fitting since it's Rin.

No, it's not. A lot of people didn't know how to get it in the beginning, though, because it's "harder" to get to than other ends, which are painfully obvious or land-in-your-lap easy. I guess you could also look at the fact that Emi and Shizune's ends have multiple ways to access, while Rin's only has one. Lilly and Hanako's do too, but theirs are really obvious.
