After starting a new game with 0.40 I was able to do everything again, (mostly, didn't bother this time with Ratking, Scrap, Hayden and Arion).
I found out that the 2nd heart for Ste is only available in Top Logan route, because in Bottom Logan route it's Logan himself who receives 'payment' after Country Road which prevents you to gain that heart moment, lol..
Anyway, what I never seem to get is the stuff with the rabbits? I read somewhere that you can fight them and even can get a game-over scene with them?
