Duuuude! Thanks for a long comment.
I dont know to what Polly refers in original, but I get him from the game Space Station 13, where he sits in engineering location and says some random phrases (my friends said that "Poly wants a cracker" is a reference to Nirvana, but im not aware of that). Feeding him with crackers was my idea, and its working as kind of a path to first ending. Ill look up the Blue series, thanks.
Yeah banana is kind of ref to Space Station 13 too.
I just tried to not waste so much players time on terminal, so yeah buttons are quite straight froward, ill remember your advice for future.
After engine started a small Singularity appeared in the green shield area. Thats an engine!
Again thank you for your reply!
