I gave the cracker to Polly. I think that's a Blue (the animated series) reference right? :D Great series. Anyways...
It took me a while to realise that there was a banana on the floor :D
It's kind of annoying that the terminal gives prompts and ask twice for confirming - there is nothing else to do. And it's not possible to say no. Not sure if that is intentional design or accident.. Can't say I'm a fan of that decision.
Not sure what happened after the engine started - sounded like it fired some projectile in some direction.
It's an interesting game - the best way to make a narrative is to give just enough information that the player is asking himself questions. Then the player wants more story. That's better than giving too much information and the player pushing it away.
Good luck!
