Listen. This is an interactive fiction game. That means that you will not get what you want merely because you want it. You will have to look thoroughly, and find clues.
Let us see what you have done so far, shall we?
You tried to command the entire town, several times. When, astoundingly, the townspeople did not obey the every word of some random person, you refused to associate with them.
You went to Dr. Donlan's house. When he didn't build you a killer robot on command, you promptly ignored him entirely and left, not even trying to talk to him.
At this point you decided that you would try to escape and panicked, as there was clearly no way to win the game other than the second person you meet building you whatever you want on command.
I commented that you hadn't explored much. You went to the tavern. Upset that you could neither kill everyone, nor magically summon a figure to tell you what to do, you left again, ignoring the barman.
You tried to get awesome weapons and armor. When this proved futile, you once again decided not to talk to those lowly NPCs unless they would do whatever you said, and went to the shack. It was locked.
And now we are here.
tl;dr TALK to people, ASK them about things, explore more areas when you don't know what to do instead of just giving up
