Just played Digital: A Love Story and was checking out the tag. Yeah that 915 number became almost muscle memory by the end. I was almost worried I wasn't going to be able to complete the game because I was running out of codes (which is the most enraging thing when you are getting really close to the end).
It definitely increases the difficulty at the end there where things start going into the final act. As far as storytelling goes it's really successful in those last few moments because while you might not be hooked in the beginning you can really see when the suspense really ramps up and you start sweating over if you can even actually finish the game using only the numbers you're provided. Plus it's just so awesome from a design standpoint, all of the pieces flawlessly falling into place like that even in the last moments (despite the frequent trips to 915-3347 and that dial tone).
Ugh, it's just such art. I could gush about it all night. I'm just so into everything Christine Love does, I want to play it again as soon as I forget everything about it. I'm glad other people are playing it too for that matter and I see you've also played Don't Take it Personally Babe, so you must just have excellent taste in visual novels.
I'm gonna read your post about that now.
