Oh, this is realy strange because game don't end when I lose all characters. Game just asks me if I whant to continue or restart. When I press continue I can't choose anybody but I still can press continue. After that I'm again on the ship and after I enter the factory I instantly lose. And loop repeats again. I think it is a bug.
my apologies!!! I had forgotten that I updated the character select screen in my last update and forgot to replace the line of code for ending 4 ! it's back in there now, thank you for bringing that to my attention!
you can go through it faster by buying the walkie for each character and investigating the monsters, thanks for the heads up!
