Thank you for your kind words!
When we were working on the script I was inspired by a quote I heard somewhere: "Sometimes I write a million funny lines just to make the sad lines sink." (that quote is heavily paraphrased, I don't remember the original) That was sort of the goal of the mixture of funny/serious - we tried to getcha to let your guard down.
And yeah about the messaging system - the original idea was to have the computer be a fully interactable, fake operating system, but we couldn't really figure out a good way to implement that in the programming sooo... Yeah. I'm not happy with the solution we came up with, but I'm glad we at least got the story working.
And sound mixing was also cut for time - we'll try to improve that in an update. (there's a really funny easter egg sound effect during the section where Salmon is gaming, but it's unfortunately a little too quiet for most people to hear)
