There must be something wrong with this game if you have to change / cheat with saved files as someone writes here. And it shouldn't be a problem for the game developer to give a few more hints about how you should play, what you should prioritize. Count on the fact that there are perhaps more people who try the game and don't get past 40% and get annoyed and then they don't want to pay for the game. This is probably something the game developer should think about if he wants more paying players.
I appreciate your concern, though I develop this games for myself, mostly. I don't care that some players don't get past it, if any of them do that's enough, and I know, that's just putting some extra work to get more players happy but in that case, I rather make a different game with this extra time that would be more bang-for-the-buck entertainment wisely.
