Wow, pretty great! I kinda wish that it were possible to increase the screen size (even if it means stretching stuff), but I'm guessing it might be an engine limitation. (Or maybe there wasn't enough time; but that's not a big deal.)
I also kinda wish the reminisce screens would always go back to the first image whenever you re-open the dialog, but oh well. It's kinda nice how it sorta loops... kinda encourages you to just stand there and figure out what's going on. But it also means you just hold still and stare for a while.
At the end, I thought the other character was dead. I sat there, looking at them for a while. And then I let go of the button and the end played. It was a bit of a relief!
