Grab the fish bowl
Go to the cockpit through the open doors
Grab the drink
Seduce the drink, to 'suck' it down, ha ha ha, get it, it took me far too long to figure this out, I had to read a comment on the update post. If i had to guess this is probably where people are getting stuck.
Put the fish in the cup.
Empty the now fishless fish bowl in the sink to acquire your helmet.
Open the fridge and microwave what's inside to be able to use to open the lever.
The key to the airlock is beside the airlock, grab it and open the airlock.
You can now go outside of the ship, but that doesn't do much with what you have right now. Get other things by just like interacting with shit.
Differences from prior walk-through, that I've noticed: The panel is outside now, there are no wires, that purpose is fulfilled by something part of the panel now, and if you open up the Toy you get batteries that you can charge.
