Huh, we actually went out of our way to put in as many jokes as possible. I guess we need to try harder next time

Also, their inability to secure the channel was actually explained later in the game, and in my opinion was funny. Did you get that far? If you did and you're not remembering it, I definitely did something wrong

Regrettably, I didn't. I tend to only be able to hold my own in puzzle games so far.
As far as this goes; I'll submit what I've learned as a writer. When a reader's question needs explaining, make sure the answer arrives as directly as possible. Until you do, the question comes off as unanswered due to failure to notice it by the writer. IE: Bob the Alien Abductee is talking with Svlaztnztl, hot green alien space babe and never once does he ask why he's been abducted, or why she can speak English (or he can speak hotgreenspacebabaneese), thus it's assumed the writer didn't give a damn. Even if it is answered eventually, the reader still is left with disbeleif for however long it takes.
Sorry for the cool story, bro.
The point is; use this as an opportunity todeliver a quick, hook joke that whams in some humor early, that would be my best suggestion. Good luck with the game, hopefully that was helpful.
