First of all, thank you very much for having read it! And I'm glad you found many aspects of it pleasurable. Your criticism of the ending isn't something I myself even disagree with. Way back when it was only in the form of a script, I personally felt it was one of the weaker aspects of the story. I can at least explain why I ultimately went with it, for any curious:
As for the flickering screens, what you mentioned was also a concern of mine. I think the effect can add a nice touch, but I'm also aware some people might be sensitive to it. I'm sure if I looked into it I could figure out how to add an option to have it on or off. Or I might just get rid of it all together, since I'm not sure if it adds that much to the overall atmosphere. Out of curiosity, did you have trouble with the flickering screen for both the half-screen computer, and the full screen one? Or was it one more than the other? Because my suspicion is that the full screen one is likely the more annoying one.
