Thank you very much :)
Well, as I've said in one of the other answers to the comments, it does seem really difficult when you play it for the first time. It's not though, you can totally make everyone survive. After you get used to the controls and give it a couple of tries, of course. In my first iteration of the concept I wanted to make the game even more difficult, or introduce some cheating move or something, so that getting the good ending would be impossible. I wanted the game to make the person playing it feel something, experience some emotion, and if everyone survives, well, it just wouldn't have the desired impact. But then I've realised that it's turning out difficult enough, so that getting the good ending on the first try is still very unlikely. So I left it at that. :)
I understand that players struggle with the controls... This is a very vasluable feedback, I'll try to remember this next time. Like if I want to make a game that is difficult to control, I need to somehow justify and legitimize it. At the very least, mention it in a dialogue (along with a tutorial, yep).
